I am training to run very fast behind my friends bike with my bow and wanted to know how many mph she should pedal. I am trying to get in shape for bow hunting season so when she rides her bike I run behind her (sort of chasing) her with my bow (not in the drawn position). She wants to know if she is in "2" and "6" and pedaling as fast as she can how fast is she going? This speed is frustrating to me though because I can not keep up (regardless of how many arrows I am carrying). Any thoughts?
