Got in a nice 5K tempo run today. It was 74 degrees when I got home from work this evening - amazing since it's usually in the 90's this time of year! It was overcast when I started and then coming home (headed west) the sun came out and I really felt it. That last mile I had to settle for run/walk intervals, but the pace for that mile was only 30 seconds slower than the first 2.1. I've been running for 7 years now and it amazes me that I can take walking breaks (sometimes walk 1/4 to 1/3 of the time) and it doesn't slow down my pace much - if any. I'm a slow runner, but not that slow - ?
