'The 4-mile Cardiovascular Challenge Workout Here is a great way to challenge and assess your level of cardiovascular conditioning. I like to call it the 4-mile challenge because you travel a total of 4 miles, how long and how you get there is up to you. Here is how you do it, depending on your level of fitness you run and bike for a total of 4 miles. If your pretty conditioned you should run 2 miles as fast as possible then bike 2 miles as fast as possible. If you aren\'t as conditioned you can run 1 mile then bike 3 miles. The idea is to record your total time and try to improve on it from week to week.'
