It's not as exciting as the title sounds but I'm still quite happy about my performance this morning. Got up at 0430hrs to walk on the treadmill with an empty stomach again. This time I managed 50 minutes (3.4mph, 4%incl, 340cal)! My previous problems with my knee and shin splints have corrected themselves which leaves me to push a bit harder. At the 30 minute mark I started to increase the incline 1% every 2.5 minutes until I got to 7%. I know it doesn't sound like much but it felt like climbing the Rockies. PT test is next Tuesday, I'm ready.
