I rode to work today as well, 27 miles.
They had a breakfast station just 1/2 mile from my house so I checked it out, got a water bottle, food & a sticker that said; I rode my bike to work today & I wore it all day.
Then I stopped at another one in Niwot that wasn't to far from my work, got some cool little things, a blinky light, & more food.
I told someone at work this is like Halloween for bike riders, it was a blast. Since I hit the first station at 6:20 there weren't to many people there, but my son drove by later & said there must have been twenty or more people hanging around. The one at Niwot had a lot more people & it was fun just visiting the other bike riders.
I was planning on riding home but for some reason & was feeling very tired & light headed & riding into a head wind made me change my mind so I rode the 7 miles to my wife's work & hitched a ride with her. I don't think I ate or drank enough water throughout the day & that might have been my problem.
