Almost been a month! Trail status is about the same, it's been mostly hot and dry. I've been in recovery mode still. Taking it pretty easy getting back into activities. Still have a couple more weeks until my wrist is fully healed but my head is feeling good. Have got a few runs in around Bon Tempe and been able to tolerate zwift sessions also. Slowly building back up.
Will try…

Happy Sunday!
Another hot day then it starts cooling off gradually starting tomorrow.
Check out the NWS Heat Risk site for a nice visualization of the hottest spots on the west coast:

Couple days of hot temps but the 4th was pretty nice in the 70s, looks like that'll continue for the week. Trails are dry but still some wildflowers around. I'm still recovering from my injuries but hope you're getting out and enjoying the summer!
June 26 2023 07:02 AM //
Warm midday but we're still getting mostly cool temps here late June. Can't complain! Lots of wildflowers out on the loop still, it's been an amazing year for wildflowers.
Trails are dry but if you get out early there is still foggy moisture in the air. Had a perfect run yesterday morning in Cascade Canyon with Johnny 🐕
June 16 2023 03:11 PM //
Alright, back to what y’all are here for! Trail reports 👊💥 Apologies for the delay since the last one, had some vacations and injuries to deal with.
Trails are very dry, like completely 🦴 dry. Nice cool weather last few weeks to slow down the spring-to-summer transition. Still some green around the loop in the shade, last holdouts before it all turns brown (err, golden) in the coming month…
May 21 2023 06:06 AM //
Sunday update - Got out for the Kooks of the Coast racey-ridey-experience yesterday. The whole event was awesome and hilarious. Totally will do that again.
Trail news - Tamo is drying up quick! Just like everywhere else. Trails are mostly dry at this point and the green fields are getting brown. I think there is a *chance* of some rain next week but we'll see.
Also checkout go…
May 14 2023 06:06 AM //
Should be a perfect nice cool Sunday!
Got out yesterday afternoon, pretty damn hot but we'll be hoping for 80s in a month.
The fields are drying out fast, get out here now for the last of the hero dirt!
May 12 2023 01:36 PM //
Warming up this weekend but still super nice out! Got out for a Deer Park loop yesterday, amazing around there right now also. Super green, lupine fields 👌 I have been on the Tamo routine lately, good reminder to change it up sometimes.
No rain on the horizon, trails are perfect right now though so hope everyone is enjoying it!
Been awesome running into people on the trails lately, …
May 03 2023 02:19 PM //
Another storm cell passing through here at 2pm and we are currently at 1.2". Rained pretty consistent over night, Tamo trails are open but probably will be more fun to ride tomorrow. I wandered around Cascade Canyon earlier and it was pretty muddy. Will drain fast though and the next week should be prime again!
April 24 2023 01:05 PM //
Weekend was sunny and warm temps, that may be on repeat for the foreseeable future ☀️
Trails are still running great but almost all dried out. Only a handful of puddles left on the loop. Wildflowers season is here, tons of wild iris especially on wagon wheel.
April 18 2023 08:39 AM //
Back from a week in western Colorado.
Trails were great yesterday and we got a little bit of rain over night. Should be perfect again today.
Enjoy!
April 09 2023 07:13 AM //
PERFECT conditions today, can't wait to spend the afternoon at Tamo! Hope to see y'all out there ☀️
April 07 2023 08:21 AM //
Rain? I don't see any rain... 🫣
So far not quite .5" since last night. Nice little hero dirt refresher for the loop. I think we'll leave the trails open seeing as it *should* stop by noon and it's just drizzling right now.
Will update the site if that changes.
April 06 2023 10:35 AM //
Marinduro photos have been delivered, what a response! So stoked for how the race went and it's great seeing everyone already excited for next year.
...back to the regular program. Tamo trails are running perfect right now. Berms have never been better. Dirt is drying fast but still great.
Nice cool temps with maybe a little rain tomorrow. Doesn't look like it'll be e…
April 01 2023 06:05 AM //
Tamo trails are closed today for Marinduro!
Come spectate, you can grab a map at Splitrock before heading up to the course. Endor will be a great spot and I will be at the rock drop on Serpentine (Segment 4). Come say hi!
March 31 2023 07:41 AM //
Ran around the loop yesterday to check on conditions. Draining pretty quick actually and as it turns out after 10+ atmospheric rivers, there aren't a whole lot of weak branches left on the trees.
Tamo will be closed today and tomorrow, but I'm hopeful we can open it for good on Sunday. Stay tuned.
March 28 2023 11:21 AM //
Another storm today so Tamo is closed again. Depending on how much rain we get it could stay closed through Saturday.
March 21 2023 10:29 AM //
Another day another atmospheric river! Crazy winter in CA.
So far another .5" at 10am. Trails were soaked before this and will continue to be soaked after this so unfortunately they are still closed. 😭
Any update to that will be reflected in the trail status below.
March 18 2023 06:47 AM //
The last few days of 60s+☀️ helped a lot but everything is still soaked. Trails are still closed. Looks like more rain expected tonight and tomorrow.
March 14 2023 07:03 AM //
Got out Sunday for a trail run/trail maintenance loop. Completely soaked. Just posted a full update on Instagram.
It's been rain every day since the last post. Looking at over an inch this morning already in the current atmospheric river. Let's hope this passes quick and we get some consistent sun!
Posting some videos to Youtube, be sure to subscribe so you get those notif…
March 05 2023 07:13 AM //
Tamo still closed. Rain in the forecast almost every day for the next week. Hopefully we get sun after that 🙏
March 02 2023 08:18 AM //
Tamo trails currently still closed. Going to head out there once it warms up a bit today and check on the loop. I imagine it's still pretty muddy.
February 22 2023 09:01 AM //
Windy and cold today. Allergy season has arrived in force. Weather is going to get crazy again the next few days...
“Up to 5 inches of accumulating snow is possible on Mount Tamalpais beginning Thursday night into Friday, according to the National Weather Service.”
Snow run Friday! wooo
I expect the trails will be closed again depending on how much rain we actually get. Stay …
February 20 2023 11:17 AM //
Super nice yesterday and today. Looks like it'll get cold with maybe some rain later in the week.
Saturday trail work on wagon wheel seems like it was productive. I was not out there but went for a run yesterday to check it out. Tons of big drainage cuts, in MY opinion overkill... but what do I know. The new rock garden setup is cool. The main line is easier now, which is nice so I ca…
February 17 2023 06:39 AM //
Trail are open and looking great. There are a few dry spots now but overall still perfect hero dirt conditions. Puddles are all but dried up, little bit of water still flowing here and there.
Doing a lap the other day I was thinking to myself, it feels like more berms than not have been rebuilt this year by Access4Bikes. It's amazing. That recently work on B-17 Extension is so sweet.<…
February 11 2023 08:40 AM //
Bit of rain this morning but cloudy and misty right now. Trails are currently open.
Got out yesterday for a run and it was perfect.
Tamo will be muddy, but lots of recent work by Access4Bikes to check out. Enjoy!
February 08 2023 06:29 AM //
Trails are open! Boy Scouts decided to open them back up yesterday.
Access4Bikes was out on B17 finishing up some work on the berms also.
60s and sunny, I'll be getting out for a run loop today. Hope to see you out there!
February 04 2023 08:06 PM //
Saturday evening post. 8pm and we're at another inch of rain on the day. Amazing.
Trail work day was awesome. Rained the entire time. One group hit mud spots with gravel on Serpentine and Goldman. Another group rebuilt berms on B17. Boy Scouts grilled lunch. I think the last planned Tamo work day for the season but the place looks so good.
Only three people caught on the trails…
February 03 2023 10:28 AM //
Run loop Monday / Bike loop Tuesday / Run loop Thursday ... some quality Tamo time this week!
For a nothing storm, we got over an inch of rain last night. Trails are going to be soaked again, which is great, they were starting to get dry in spots.
Boy Scouts made the call, trails are closed at least for today. Will update as soon as they reopen.
January 30 2023 10:31 AM //
Another super productive Access4Bikes trail work day on Saturday. Lots of work done on Alchemist trail and a small spot on Goldman as well. Installed pavers, spread gravel and pulled a ton of broom.
Great seeing and meeting everyone. Huge props to the students from Terra Linda and Redwood! So awesome to have a community like this contributing to these trails.
Trails are looking ama…
January 28 2023 08:08 AM //
Nice sunny Saturday ☀️
Alchemist will be closed from 9-12:30. Access4Bikes will be out fixing up the trails.
Enjoy!
January 26 2023 07:18 AM //
Another January spring day! 60s and sunny, yes please!
Got out yesterday with Ted. Who is a real life, often seen in newsletters and seldom seen on the trails, "Friend of Tamarancho"! Had a great time hearing some of the history of the trails and the Boy Scout mountain bike program. Super nice guy.
Trails are still in great condition. I'll be out there again today, en…
January 23 2023 09:12 AM //
Tamo trails opened yesterday. Got out in the afternoon for a loop. Conditions are awesome.
Definitely some mud spots but actually less than I had expected. Otherwise the trail is perfect. Tons of new berms from recent A4B work are super fun.
Ran into Chris, Chad and Eric. Played leap frog a couple times on Serpentine and Wagonwheel then rode Broken Dam and Goldman together. Was sto…
January 22 2023 09:03 AM //
Tamo trails are open!
Just got the word, site is updated. Time to cancel everything I had planned for the day... See you out there!
January 20 2023 07:53 AM //
Another sunny day!
Tamo trails are still closed. I expect they will need at least a few more days of sun.
The site will be updated as soon as I hear anything!
January 18 2023 08:11 AM //
Cloudy today and looks like we may get a bit more rain this evening but yesterday was perfect and more days of sun on the way!
I went for a 680 loop yesterday. Fire roads have lots of muddy spots but it was all rideable and good fun. The green rolling hill view from the top of Loma Alta is pretty amazing right now. Wild flower season is going to be epic up there this year.
Have not …
January 17 2023 07:54 AM //
Sunny and no wind, I'll take it!
Looks like the Wednesday storm is maybe petering out a bit also.
I hope this wasn't the last of our winter rain, but I'm not complaining this week.
Enjoy!
January 16 2023 08:28 AM //
Looking like we may be through it! Bit of wind today but looks like we're going to have some sunny days this week.
Got out to J2 yesterday during a break in the storm. Red tailed hawk was up on top of a tree again hunting in the meadows. Beautiful day.
I'm going to try to hike the loop in the coming days to check conditions.
Stay tuned and enjoy the sun!
January 13 2023 10:24 AM //
More rain today. Dumping since about 7am. Over an inch so far.
Checked on Serpentine yesterday. Drainage work before the storms helped out a lot. With a few sunny days most of the downhill will be prime. It does look like sun next week but we got more rain until then.
January 12 2023 08:34 AM //
Another 3.3" of rain in yesterday's storm. Wind was absolutely crazy yesterday evening, thankfully we did not lose power again.
Today looks like it'll be perfect! Definitely going to get out to J2 to check on the trails and try to get out for a ride also. Hope you can get out to enjoy it.
Looks like more storms for the weekend.
January 10 2023 10:36 AM //
Rain everyday and the winds have been crazy. Lost power the last couple nights for about 10 hours each time.
Haven't been out to check on trails the last couple days. Today the sun is peaking out but sporadic heavy rain so far this morning.
Got out to Cascade Canyon on Sunday, incredible how much rain is in the creek. Fairfax Falls has gotta be epic right now.
January 07 2023 08:29 AM //
Little bit of rain overnight, picking up this morning. Going to be another wet few days.
Got out to B17 and Broken Dam yesterday. A few new trees down but mostly off trail. One pretty big one on Broken Dam. Also that low hanging tree on B17 just before the switchbacks is about 4' off the ground now.
Drainage work has definitely helped.
Trails are completely littered with…
January 06 2023 10:11 AM //
Yesterday afternoon I thought the storm was mostly past. Was planning to do a full loop (on foot of course) to inspect all the recent work. Got out to wagon wheel and got caught in a quick deluge. Wind picked up so I decided to head back to J2 and was rewarded with an incredible sunset. Kicked open lots of puddles on the way.
The trails are littered in tree shrapnel, definitely not safe to…
January 05 2023 11:16 AM //
Power has been out since last night, just came back on about 30 minutes ago. Super windy all night but has calmed down this morning.
Storm totals are less than predicted but still probably 2"+ in the last 24 hours.
Still raining.
January 04 2023 07:50 AM //
Already an inch of rain since midnight and we're just getting started.
Got out to scope Serpentine and Wagon Wheel yesterday, no trees down but lots of puddles. Met up with A4B for trail work on Broken Dam and B17, removed a bunch of downed trees and fixed drainage. A couple huge trees down on upper Broken Dam all clear now.
January 03 2023 08:33 AM //
Got out to J2 yesterday and cleared out some drainage on Serpentine just before the rain started. Trails are soaked.
Weather station shows .78" in the last 24 hours and the big storm starts tomorrow!
Stay tuned.
January 02 2023 07:22 AM //
Perfect day yesterday after the storm and an amazing sunrise this morning, but we have more rain arriving any minute.
Looking like major storms lined up for the next week or so, I may try to hike out to J2 to get some pictures later this morning.
Hope everyone got out yesterday!
December 31 2022 08:57 AM //
EDIT: 4:30pm - 6.6" storm total currently
8:13am - Since I posted yesterday at this time it has been pretty much storming non-stop. I estimate around 2.8" of rain in the last 24 hours. It really picked up on schedule yesterday afternoon around 4pm and poured all night. Will be interesting to see what Marin Water reports.
Storm total here is about 4.5" at 9am.
I…
December 30 2022 08:11 AM //
Consistent rain overnight, the main storm arrives today. Yard meter is around 1.7" for the storm total.
Will keep you updated on the daily rain totals, working on some integrations for the site also. Stay tuned.
December 29 2022 09:05 AM //
Rain! Around 0.25" of rain so far and more on it's way.
Got out to Lake Lagunitas yesterday. Water is flowing everywhere, really amazing out there right now. The next week is going to be prime time to checkout Cascade Canyon + Fairfax Falls, though you'll need to ford a river or two.
Will keep you updated on the daily rain totals, working on some integrations for the…
December 28 2022 07:42 AM //
Beautiful sunny morning. Next set of storms start coming in later today. This time tomorrow it should be raining again and probably continue through the new year.
The last storm brought around 2.5" of rain in less than 24 hours. Trails are still soaked and Tamarancho is closed.
Good day to cruise around Lake Lagunitas, the redwood forest will be spectacular.
Enjoy!
December 27 2022 11:01 AM //
Got out yesterday afternoon for what I suspected, based on the weather forecast, would be the last Tamo loop of the year. Perfect conditions... today, not so much.
I walked out to J2 earlier to check out Serpentine. We're at about 2.5" of rain since last night, the trails are mud slide conditions right now.
They are officially still open if you check the Boy Scout website …
December 26 2022 07:49 AM //
Christmas and Christmas Eve were perfect sunny warm (for winter) temps. Today is looking like it'll stay foggy all day right into a series of storms throughout the week.
Trails are still open and running great, we'll be staying tuned for any closures.
Enjoy it while we can!
December 24 2022 08:32 AM //
It's been cold and overcast the last few days. Sun is coming out today, trails are still prime conditions, should be a perfect Christmas Eve!
Enjoy the holidays!
December 23 2022 03:36 PM //
TLDR; Trails are open and awesome
I've made it out a few times since the trails opened back up. Everything is running really nice, only a few puddles in random spots around the loop.
The trail work on Serpentine looks great, I have not made it down to Alchemist to see the new berms yet but I hear they are 👌
Highlights are definitely B17 and Endor. Conditions are PERFECT …
