Use a little common sense....it's obvious he meant 1.5 miles.He never said whether his 13.5 min 1.5k was actually supposed to be 1.5 miles. 13.5 minute 1.5k translates in to about a 22 minute mile and a half, so if thats true there's no amount of pushing your walker around the neighborhood that is going to get you in shape for the PRT... Unless you happen to be a Master Chief...
