Note about that picture. I

Note about that picture. I may be mistaken, but I believe that that picture is from an SI diary. It is the bustop ride exting Boulder. The girl up front wanted to make the olympic team in 2008 in a sport and she decided that she would do it in cycling. SI was to do a series on her attempt and I only read a couple of the entries. Note, this was about 12 months before trials. She moved to Nederland to train at altitude but often came down to Boulder to ride with groups. She knew that they were going to take this picture and this is the ONLY time that she was near the front.....or even with the group. There was another girl on the ride that night, one that is a regular and quite capable of staying with the main field.

I found the SI girl to be overly confident, naive and the series was short lived.


Loops is a Tuesday night bike ride through out central Denver. The ride covers approximately 15 to 20 miles and makes 3 to 4 stops along the way. Riders are encouraged to ride at their own pace and meet at the stops that are posted on this blog the day of the ride. The ride meets every Tuesday night at Crema Coffee House (29th & Larimer) Come out and ride with us, make friends, and have a good time.

Riding N/E of Denver - good stuff!

Hi, I've been riding north east of Denver lately, man, what a treasure! LOTS of roads, lots of DIRT roads, very light traffic. I'm convinced some of those small rural county roads go to Kansas. Are any of you riding out this particular east of Ft. Lupton. It's taking me some time to "map out" as the terrain is so vast. When I look at the popular mapping sites, they don't give much useful info. Any feedback appreciated! Thanks.
