Take a nice 25 mile trip. Set your pace-enjoy creation.
15 Miles an hour is 4 minutes a mile ;)
Compare to 10/15/15's workout
During your mountain bike ride, no matter the distance, wear ankle weights.
Wear a backpack if you need to store them during the ride,
mark the distance you made it to before you took the weights off
Life on Two Wheels!
Get ready for a bumpy ride, workouts may be deceiving!
