Before I start…1) Yes, I’m an older guy which are pretty much despised here on LR so get your jokes in now. 2) 16 minutes is good, but not great for LR. I am not talented.
Started running about five years ago at age 34. Got the running bug after watching the 2016 Olympics and started jogging after that. Entered my first 5K in June of 2017 after 10 weeks of training at 20mpw and ran 20:30, getting dusted in the last mile by two high school kids. I continued to add mileage (35 mpw) during the summer and ran 19:35 at a Turkey Trot in 2017.
Trained harder from January 2018 to May 2018 (50 mpw) and ran 18:25 on a cool summer day. My training during this period was 4 mile tempo runs, 12 mile long runs, 5x1000’s, and some hard 200m reps. I also found a parking garage with a good incline and would literally run up the whole thing as hard as I could about 10 times. I built up to 65 mpw during that summer and in October 2018 I ran 17:40.
Here’s where I stalled. From 2019 through 2020 I felt I could just keep running 65mpw with harder speed workouts and see big improvements. I increased my speed volume, but not my overall mileage. I continually got struck in the 17:20-17:40 zone for about a year and was close to throwing in the towel. COVID struck and I also got a bad soleus flare up and IT band problems for about a month.
In late 2020 I decided it was all or nothing. I built up slowly from 45mpw to 80mpw from October to May 2021. I kept at 80mpw for a 7 week span. Nothing really changed in terms of workouts although I entered a few 10K’s and used them as tempo runs. I was still doing 5x1000’s and 3x1 mile repeats. I just increased easy mileage. Easy pace throughout the build up was 8:00-8:15 pace and at the very worst 8:45 pace.
Ran a disastrous 17:48 in June 2021 in my first race off the 80mpw and was incredibly depressed and angry. Maybe I was still reeling for the higher mileage? I signed up for a September race and kept the mileage in the 70mpw range up until the week of the race, which I cut down to 30. I knew I had a shot at 16:30-ish based on the workout the week before but you are never really sure until you are actually in the race and feeling things out.
We had great weather and sure enough, I ran 16:25 and was absolutely over the moon. I ran 16:41 two weeks ago just to see if I could break 16:30 but went out way too hard.
I guess I’m here to simply say that mileage works. I have no real talent. I know guys running far less mileage and running much faster. I hope this post motivates a few people to stick with it and keep building mileage. But one of the greatest things I took out of it was mileage correlation….
TL:DR Average Mileage/Times correlation for untalented runners:
20 mpw - 20:30 5K
35 mpw - 19:30 5K
50 mpw - 18:30 5K
65 mpw - 17:30 5K
80 mpw - 16:30 5K
Sorry for the long post, but this is LR, where you can run 80mpw and have your dreams become reality.
