walk/jog 52:00 
TNT - track workout. Mixed things up, walking and jogging and trying to run the last 100m hard every other lap and then every lap. Alternated hard/easy laps where easy meant I could walk the curves. Did the hard ones in 2:15-2:30 and the easy ones in 3:25-3:40 for a total of 14 laps. Plus the walk over to and back from the track. Happy with the results.
