MY commute is about 16km. I am located in Vancouver so I am making use of the Central Valley Greenway. It is a mixed of bike lanes and parkland gravel paths. My ride is a 07 Norco Mountaineer MTB with a Blackburn rack to carry my knapsack. No fancy panniers yet. Maybe one day.
I don't know if I still qualify for this thread as my times have been steadying declining to under 45mins since I started. My goal is to go down to about 30-35mins. Given that my stock tires are knobby rubbers, I don't know if I can achieve that.
