Then came Sunday. I was scheduled to run 7, walk 1, repeat 4. The day was beautiful -- 60 degrees and sunny. Up until then my standard run took place in 30-degree temperatures or less. Sixty would be awesome! I threw on shorts and a T-shirt and headed out the door.
Right away, I could tell something was amiss. Barely one minute into it, I was breathing far more heavily than normal. I slowed my pace and pressed on, making it about 6 tenths of a mile until it was time to walk. Halfway through my second 7 minute jog, I had to stop and massage my tight calves. I tried jogging again, but I was so easily out of breath. What was going on? Why was this so much harder? Halfway through, I cut my losses and walked home.
Why was it so hard? It could have been the poor nutrition I expose myself to on the weekends. It could have been the fact that I was trying to run less than 24 hours after a particularly strenuous effort. But after some discussion with Diana, I realized that the fact it was 30 degrees warmer than normal probably had a huge impact. Apparently my body has become acclimated to exerting itself at cold temperatures, the sudden increase was too much for my wittle body to bear.
Tonight it's supposed to be in the low 40s with a little rain. The plan is to run 8 minutes, walk 1, and repeat 3 times. We'll see what happens!
