I started running about a year ago and I really enjoy it. Most of the time I run on treadmills before my workout, but when I can I love to run at parks. My roommate and I had a race my last semester and he zoomed away as soon as I reached my limit. Would appreciate any recommendations.
Edit: Thank you everyone for your responses!
Do you want to increase your burst potential over a shirt period, say 30s-1m, or your potential for longer stretches, say 30m-1h?
