The feedback from this comment has been amazing. You are all awesome.

Thanks for sharing your sprinting knowledge.

My workout usually includes a 5 minute warm up period, followed by about 15 minutes of running as fast as I can that day. From there I usually hit the bike for a cool down and to burn extra calories.

I never did this on purpose. I did it because I love the feeling of having your heart in your throat. Apparently I am not the only one.

Thanks again!
