Today I did my first 20 mile (33km) ride on my hardtail XC bike. I learned how to ride a bike about 1.5 months ago, but I’ve been riding pretty consistently since I learned. I ride exclusively in the city, it’s a very walkable city, but the paths aren’t always the best. I did 33km in 2 hours 53 minutes, not including breaks for water or to eat.
I see people saying that 10MP/H (16KM/H) average is a good average to shoot for, but i can’t even get my average above 7.1MPH (11.5KM/H), even on shorter rides. What am I doing wrong here? How are people going so freaking fast on bikes in cities?
This might be part of your answer. Modern mountain bikes aren’t nearly as good on the road as vintage ones were.
However, don’t replace your bike before you check your technique. Did you get a professional fit when you got your bike? If not, did you talk with anyone experienced about setting up a bike for a comfortable riding position? Bikes do NOT come out of the box or out of the aisle set up well for most people, and it’s not always intuitive what the best position for you might be without experience.
Average speed is going to be highest when you can maintain pace. Straight, flat paths with few stops. Are you able to find a stretch of, say, 2 miles that has few to no deviations or stops? Including curves - if you have to slow down and then accelerate again, that’s inefficient and will tire you out.
How’s your tire pressure? Rolling resistance is greatly affected by tire pressure.
Gears? Are you able to pedal at your most comfortable speed of pedal rotation at a maintainable pace?
I’m by no means a pro - I’m also old and overweight, but 10 mph average over a long ride comes very easily when I compensate for those factors.
