Sourdough Trail

This Thursday, July 1st we are headed up to the mountains to ride the Sourdough Trail off the Peak to Peak Hwy. This trail is a six mile out and back (12 miles total) between the UofC Mountain Research Ctr. and Brainard Lake. This is a challenging ride with lots of rough, rocky terrain. We will break into two groups. Each group will determine how far they go out and back based on the abilities of the group. This will be a great opportunity to work on your technical skills, so don't be shy about coming out.

Meet at The Justice Center parking lot at 6th and Canyon in Boulder to carpool. This will be a late night, so I’d like for all the carpoolers to leave Boulder by 5:15p. I know this time can be a challenge with work schedules, so please plan accordingly and see if you can leave a few minutes early (maybe go in early to make up for it). If you can’t make it to the carpool spot in time, please meet us at the trailhead and be ready to ride at 6:00p. If this is your first ride with us, please print out a liability waiver (below) and bring it with you.

The map isn't very detailed so here are the driving directions:
From the intersection of Broadway and Canyon in Boulder, go 16 miles west up Canyon Road (Highway 119) to Nederland (you could also take Sugarloaf Rd to the Peak to Peak Hwy). Take the second exit from the traffic circle, heading north on CO 72/Peak to Peak Highway and go 7 miles north. Turn left onto County Road116 (there is a sign for the University of Colorado Research Station at this point) go about .5 mile to the parking lot on the left, trail starts across the road. (Map)

It might be difficult to get back in time for dinner, so we’ll play this by ear……

White Ranch--this will be a hot one!

This Thursday, June 24 we will head south and tackle White Ranch. As with past rides, we will break into 2 or 3 groups. Everyone will meet at the lower White Ranch Trail Head off Pine Ridge Road. To get there, take Highway 93 south from Boulder toward Golden. After the stoplight at W. 58th Avenue, take your first right onto 56th Avenue. Follow 56th until it Ts at a stop sign, and take a right. The parking lot will be just ahead.

First, I need to ask for a few volunteers to help out with this ride. We lost some of our regulars for this week, so we are short on leaders and sweepers for additional groups. If anyone is familiar with the Belcher Hill trail and would like to lead or sweep, feel free to email or post in the comments.

One group, those of you with experience riding White and feeling sprightly, will make its way all the way up Belcher Hill. Make no mistake, this is a serious slog, so don't worry if you're not feeling up to it--there will be other opportunities to bust a lung. This group will probably descend one of the more technical trails back to the bottom, so if you are not comfortable riding down the Bitterbrush trail at Hall Ranch, it may be better to join one of the other groups for the day. We will break into one or two more groups which can spin up Belcher for as long as they like, then head back the same way (the ride down is fun!)

If you would like to carpool, please meet at the Whole Foods parking lot (Broadway and Baseline) at 5:15PM.

Dinner and drinks TBD after the ride.

  1. All riders MUST wear a helmet, bring water and bring a trail ready bike. Riders should also carry the usual basics; spare tube, a pump, tire lever, a chain tool and basic Allen wrenches.

Great Ride at Walker and Myers

Sixteen ladies came out for a beautiful evening to ride Walker and Myers. It was one of the best rides I've had this season! Super fun trail, super fun group! Here are some pics. You should come out this week for the ride at White ranch (if you are a girl).


Walker Ranch/Myers Homestead

This Thursday, June 17 we will take advantage of the long days and ride Walker Ranch and Myers Homestead . As with past rides, we will break into 2 or 3 groups. We will meet at the main Walker Ranch Trail Head off Flagtaff Road (not the Myers Homestead Trail Head the group met at the last time).

One group, those of you with experience riding Walker and feeling zesty, will make its way around the entire 8 mile loop. Don't let distances deceive you; this trail will take a fast moving group until almost dark to complete without any mechanicals! At least one other group will take it easier and ride the connector between Walker and Myers Homestead, riding out on as far as the group wants and then coming back the same way. If we have enough ladies, a third group may head out part of the way on the Walker loop, turn around and head back the way they came in time to finish by 8:15PM.

If you would like to carpool, please meet at the Baseline/Broadway Whole Foods parking lot at 5:25PM.

Following the ride, we will have dinner and drinks at Larkburger on Arapahoe.
