What is a good off season training regime for a u14 girl playing in the top division of her state? Anyone have links? She wants to substitute biking for the running her coach is prescribing. Any opinions? How far should she bike (and how fast) to be the equivalent of a 2 mile (16 min) run? The coach is asking the girls to run 1 and a half miles every day. He want them to eventually increase it to 4mi every day before school. Opinons?
