It's time for me to be a runner, not just a jogger. I've done a pretty good job of turning my non-running-self into a distance runner. Last year's 26.2 proved that I can go pretty far as long as I keep my pace slow. Each race since then has been slower and slower.
So now it's time. It's time for speed. I don't have any distance races planned for the rest of the year, but there's the ever-present 5k. It's already a challenge to change my mind-set to a shorter, more frequent run schedule. My first 20 minute interval workout today was jarring. I came home sweating harder than any of my 90 degree runs last month.
The other change is running until I'm out of breath. I'm used to keeping plenty of gas in the tank to finish a long run and cruise into the house with tons of energy. Now, with only a 20 minute run, it's ok for me to recover for 30 minutes.
