Another early morning session

I couldn't go running at lunchtime as I had to go a see the dentist and his sidekick the hygenist for my six monthly check-up. This meant an early morning session on the treadmill. These are not fun, your still half asleep, the gym is cold and you struggle to get into the swing of things. The session was another batch of threshold intervals pushing me up to my VO2 limits. This time instead of 4 * 5 min it was 1*10 + 2 * 5:30. I finished feeling OK but as the day has gone on I've been tiring. Tomorrow is a rest day so I can recoup my energy before Saturdays long slow run.
