We brought a classic back from the archives. The Interval Challenge is a workout created by Ross Enamait and I used to put this one in the mix quite often. We lost our privileges at the track that was close to my old house, so track workouts like this kind of took a back seat. However, I now have a school a few hundred yards away that has a beautiful 200 m track.
This morning we did an indian run to the track then hit the Interval challenge
Run 400 m
x 4 rounds for time
Matt G finished this with the top time of 13:45.
