Having fun riding Angora Ridge in South Lake Tahoe. Also practicing flying and capturing with my new DJI Mini Pro 3 aka Droney III.

2017 Grasshopper Adventure Series #3 Super Sweetwater

Mon, 06 Mar 2017 03:09:50 +0000

Mig created a monster with this version of the 2017 Grasshopper Adventure Series Super Sweetwater event. To add to the fun, Mother Nature brought rain to the party. And if it wasn’t raining it was misting. And cold. And then there was a lot climbing.

But there were two route options this year. The first was the classic route that included the dirt and river crossing of Old Caz. This totaled around 70 miles and 9000 feet of climbing. Then there was the alternate all road option for those afraid of getting their booties dirty (insert sad face). This had 78 miles and 7163 feet of climbing.

2015 Annadel Mountain Bike Race

Tue, 29 Sep 2015 06:07:14 +0000

A little late in the season but the timing worked out well. The fog rolled in the night before and the temperature was perfect for the 2015 Annadel mountain bike race.

Caught a few moments here and there from the race. Battery gave up the ghost shortly after the Lawndale descent.

Always a good time at this event. Bike Monkey does a great job running this and all their other events.

2015 Boggs Funduro

2015 Boggs Funduro

More pictures here: 2015 Boggs Funduro

I raced all three days and enjoyed and suffered the whole time. The new 8 hr course was a blast but definitely a butt kicker compared to the previous year’s. The hill climb hurt and then came back to remind me through the ache in my legs and lungs. The Super-D was a screaming great time.

The social side of the whole weekend also eases the pain of the racing. Bacon hand-ups, BBQs, random camp fires, lots of great people, it all rocks.

2014 Annadel XC Mountain Bike Race

Wed, 20 Aug 2014 06:18:25 +0000

The mountain bike racing season is wrapping up and what better way to send if off than the Annadel XC race. And this year the weather was playing along and kept the fog around later than normal. That gave us a nice cool feeling for the blistering fast start. It wasn’t until heading up through the middle of the park when the sun really started to pop through and begin the slow roast. No matter! It’s racing and it’s a blast.

2014 Lake Sonoma Series - Race 2

Thu, 29 May 2014 10:00:28 +0000

Had the chance to head to Sonoma for the 2nd race of the 2014 Lake Sonoma Series. This is a very fun but tough event. The riding there consists of single-track and fire roads. The single-track is a blast but tricky, rocky in places, with loose gravel, and thick dry grass. Oh, and the climbs are short steep and punchy. The promoters put together a great deal with the race and a BBQ and drinks afterwards. Always a fun crowd of all categories mixing it up.

Blast From The Past - NORBA Nationals Downhill at Mount Snow VT

Sun, 01 Dec 2013 02:26:35 +0000

Vermont NCS Downhill

Just found this photo of me from 1997? during the NORBA Nationals downhill race at Mount Snow Vermont. That’s my Intense M1 and one of the first inexpensive long travel forks (6"!) from Zzyzx. That was a tricky fun section of the course where we dropped down a fire road and then cut off right over a small hump. The speed and trajectory caused you to float sideways and almost off the course. In the photo you can see the launch point to the left where the grass is kicked up. I’m a couple of feet off the ground at this point and drifting to the left. Wow that was fun…

Winter Rain Is Finally Here

Wed, 20 Nov 2013 16:40:13 +0000

2013 Annadel Mountain Bike Race Video

Thu, 29 Aug 2013 15:15:37 +0000

The Bike Monkey crew has done it again. This year’s Annadel race was a blast. Crazy fast road start from downtown and straight over to the park. Lots of great single-track. Some ripping fast descents. Weather was nice to us. And at the finish there was beer and food waiting.
Great job everyone!

2013 Grasshopper Adventure Series - Lake Sonoma

Fri, 21 Jun 2013 15:51:38 +0000

This is the final “training ride” of the series and it’s a mountain bike event… well, except for the rare few that might bring their cyclocross bikes (rock on oh crazy ones!). The trails around Lake Sonoma are a mix of single-track, double-track, some fire road, and a whole lot of pain.

We all hear that ‘What goes up must come down’. The route here gives strong support for this saying since it reinforces it hundreds of times over and over and over. Climb up, drop down, climb up, drop down, climb up, climb up… oops, ok, there are moments where the course tricks you and ‘what goes up’ must go up some more. Ouch!

2012 Lake Sonoma Ricochet Race 4 Video

Wed, 29 Aug 2012 14:42:12 +0000

Here’s the final race of the Lake Sonoma Ricochet series.

This time the fog stuck around until just before the 10am start. That kept it a nice temperature throughout the race. And then after the race, as always, there was the BBQ, Lagunitas beer on tap, drinks on ice, and lots of raffle swag.

2012 M5 Murphy Mack's Mendocino MTB Madness Video

Tue, 31 Jul 2012 14:40:05 +0000

Created this little promo for a great event up in Mendocino.

August 24-25, 2012

This is the first time that the Mendocino Woodlands State Park has ever allowed a mountain bike race on their property! THE ROUTE IS FANTASTIC!

It’s about 10 miles per lap with roughly 1800 feet of vertical per lap. Two ups, two downs. The climbs are littered with passing areas and there is one choice of short/steep or shallow/longer for you each lap as well. The downhills are like bobsled runs. We are grooming, pruning and manicuring the trails between now and race day. Buff, smooth and fast. If you’ve never raced singletrack before, this is a great route to jump into it on. If you are superpro you can make it as terrifying as you like, simply by going faster. NOTE: 810mm bars not recommended.

Lots of wind, rain, some hail, and spots of sun during the day. One gust knocked the camera over (sideways shot).

2011 Annadel Mountain Bike Race

Mon, 15 Aug 2011 15:17:40 +0000

This is a race destined to become a classic and a favorite amount NorCal racers. The madness of a mass start, blasting through Santa Rosa, variations in terrain, climbing, fast flowing single track, and beer and burritos to finish. What more do you need?

Oh, and this year’s race helped Annadel State Park by donating 100% of all profits to keep the park open.

2011 East Bay Hills Mixed-Terrain Rally Cat Video

Tue, 07 Jun 2011 15:35:36 +0000

http://eastbayalleycx.blogspot.com

This “rally” included a mix of city riding, semi-rural roads, fire roads and single-track. The East Bay is very hilly and this was no exception. Steep hill climbs, bumpy downhill dirt descents, dirt climbs and whatever else can be thrown at you. Bike of choice is the one that you will have fun on and will get you through the course safely. A cross bike would do the trick, but so would a nice hardtail with skinny tires. Hell, even a road bike with fatty tires will suffice, although not recommended.

2011 Grasshopper Adventure Series #5 Sweetwater Video

Sat, 04 Jun 2011 03:40:09 +0000

The description begins:

Road bike? Cross bike? Your call. Pick the one that’s working best and has happy climbing gears East side of Sweetwater is a beast. Make sure you have fresh rubber and good brakes. The descent on Sweetwater has some REALLY tight corners.

And so it was. Another classic ‘hopper that gave us the ups and the downs. The sun and the rain. And the fun and the pain.

2011 Berkeley High MTB Team Hill Climb Time Trial #3 Video

Thu, 12 May 2011 21:21:21 +0000

Third and final hill climb time trial of the season for the Berkeley High School MTB Team.

It’s just over a mile long and 510 feet of climbing. Riders were started at 30 second intervals.

The start is the gate at the junction of Quarry and Big Springs where they meet South Park road. From there you head across the parking area and up Big Springs fire road (south). Upon reaching the ridgeline, take a left at the intersection and continue to the peak. Watch out for the false summit, it fools many.

2004 Tamarancho Trail Pass

Sat, 06 Dec 2003 03:00:03 +0000

I just got my 2004 Tamarancho trail pass. It’s been a couple of months since I road those trails. This motivates me to get my butt over there and have some fun. Maybe a little video of the trails is in order?

Check out the Bicycle Trails Council of Marin site for information about the trails and how to obtain a pass. Well worth it for anyone that rides frequently in the Marin area. Sad though that we have to pay for riding single-track in the birthplace of mountain biking.
