Am I insane???

I've been going to the gym each morning this week...it's been great, as hardly anyone is there (on holiday still I suppose).

This morning I got up and went to the gym, burnt 450 calories doing cross trainer, cycle and treadmill, and headed home. As I was driving past Hagley Park, I decided to stop and run the 3.5km run I've been doing...I did it in 20 minutes! Which is pleasing, considering it is my best time, I haven't run since boxing day and I'd already been to the gym.
