41 YOM only been running 10 months hadn't ran since high school. July I was 284, now 238. Using runna new to running program. I've hit a plateau I believe and don't seem to be getting faster or better. Yesterday I did 400m repeats 2 sets of 3 with 60 seconds rest between, started with a 1.5 mile warm up and finished with a .5 mile cool down. 14:21 mile 1, 15:10 Mile 2, 15:59 Mile 3, 17:27 for the final .62 miles. What's my issue? Temp 83 and this was after a 12 hour shift at work
