I was told the Bolder Boulder (Boulder Colorado) is the biggest. I came out here to ride mountain bikes and I hear 50,000 people do this race so I signed up. Anyone know of a bigger race.
peachtree 10k in atlanta.
Cool you signed up. Have a great race. I believe it is the nations largest memorial day tribute. Make sure you hang out for that.
I think the City to Surf in Australia is bigger?
