Ladder Intervals

Wednesday did a real tough work out. Me and Rick went to the track and ran a ladder interval workout. We went up and down the ladder, doing a 400. 800, 1200, 1600, 1200, 800 and a 400. I started out too fast. I was almost 20 seconds slower on way back down. Real tough work out. I think I started out too fast cause I couldnt held close enough. Its the first week of training for Akron marathon. Im hoping things, mostly my shin splint gets better. After yesterdays run I realized im not in has good shape I thought I was.
