Road or mountain? FC has a TON of great rides. For road, you have to do Rist Canyon, a crazy climb that is known throughout the front range. There are path throughout the city and tons of trails. You can email me at NLTrnzow@aol.com and I'll forward you some maps. Let me know if you'll be in town long enough to say hey and maybe we can get together for the best micro brew in the US!
