Hi I am looking for some outdoor sprinting workouts..Do you have any to share? Timed ones~I don't have a track!

Sled sprints, hill sprints, rock and sandbag sprints.

Or sprint 30 seconds then jog 30 seconds, repeat a couple of times to start with then when your conditioning improves aim for eight all-out 30 second sprints. Pretty good interval workout for endurance and fat-loss.
