The C25K program consists of three workouts per week for nine weeks. This is the results of the workout for week four, day one. Program: Brisk five-minute warmup walk. Then two repeats of: three minute run, 90 seconds walk, 5 minute run, two and a half minute walk. Brisk five-minute cool-down walk. Result: I completed the workout as planned. My heart rate averaged 136 bpm and peaked at 157 bpm. Including the warm-up and cool-down, I did 1.97 miles in 33:10 for an average speed of 3.57 mph. Combining the start of week four and a change to a morning workout, this workout really wore me out. I began struggling part of the way through the first three minute run segment. Tapping into my newly found abilities, forged through prior workouts, I pushed through that run segment and the remaining run segments. With the feeling of additional difficulty, seeing the uploaded workout results was a pleasant surprise. Average speed and distance increased compared with week three. It certainly felt like I was going slower than before. But, I’ll take it. To make 5K in the same amount of time, I will need to up my average speed substantially. I’m less than half way through the program. Perhaps I’ll make it yet.
