Week 6 was a couple of split run/walks and a 25 minute run on the weekend. Everything felt ok after breaking the 20 minute milestone. The long run was interesting as I began to notice a pattern. The first couple of minutes felt easy, then I began to get out of breath. From about 5 minutes on, everything was hard, but after about 12-15 minutes it started to get a little easier. But, no sign of that 'runner's high' yet!

Happily, there was no sign of that headache. Dr Google's other ideas on it were dehydration, caffeine and hangover. So I make sure I drink enough water, limit my guzzling of coffee before runs, and run late in the day if I am hungover.
