I use it to make pictures.
And I've noticed these pictures provide an excellent illustration of the difference between the effort you exert while biking versus running. Allow me to explain.
|Exhibit A: Output from a cyclocross race on 1-30-11.|
Note: I finished 4th in this race. The total number of participants is unimportant, but I can assure you it was more than 4.
|Exhibit B: Output from a mountain bike ride at Kickapoo on 1-22-11|
|Exhibit C: Output from a 70 mile road ride on 9-26-10|
|Exhibit D: Output from a 6 mile training run on 1-29-11|
The point? I think doing both cycling and running workouts is very good for me.
