I ran an awesome 5 miles today. I planned to do 5 miles at a 9 minute pace, but with a catch. I wanted to fartlek. I set my garmin to the average pace setting and did a nice 9 minute mile warm up. For miles 2-4, my goal was to keep my average at 9, but run random distances faster. I ended up doing the three miles faster than planned (8:39, 8:33, and 8:46), but the concept at least was a success. Each mile, I’d run comfortable for a bit, then run faster. Then I’d slow down until my average pace was back closer to my goal speed and then run fast again. That, combined with the hills in my neighborhood, was quite a workout! I then did a mile cool down a little slower than 9 and ended up doing the five miles in 44:12.
