I hate the treadmill. But I also want to get fit, which isn't going to happen on 20 mins running. Hit the cross-trainer for 40mins hard effort prior to jumping on the T-mill. Will only have to do this for another 2 weeks before I can head straight to the cricket fields for the run (only allowed following May 1st). Just as well as the T-mill has a pre-programmed max time limit of 20 minutes; convenient for this week, total balls for in general.
