Looks like one killer hill!
If you want a tough, challenging interval workout…try hill intervals! Outside or on the treadmill. Start slow and work your way up, both in speed, and quantity. Find a hill that you can run up in 30-60 seconds, and start with 3-5 reps, and work up from there. Don’t worry about speed to start, but focus on maintaining good form. I always like to think that a rope is attached to my waist that is pulling me up…or for really steep hills I just repeat in my mind that I’m running on flat ground (kinda works??)
If you decide to do it on the treadmill, depending on your level, set the incline anywhere from 6-10%, and do a 1 min run at a comfortable running pace (not sprinting all out). Again, start with 3-5 reps with 1-2 min rest in between, and work your way up.
I love doing hills for interval training…challenging and satisfying!
