Short Version: A coworker who runs every day but had never done any sort of workout starts doing workouts for 3 months and sees zero improvement in race time.
Long Version: A coworker of mine told me about a streak he had going of 2+ years of at least 3 miles running every day. Occasionally, on weekends he would run longer. Usually only 8-10 miles but he had gone up to 20 miles before when he felt like it. No workouts ever, just running by feel. Most of his runs ended up somewhere in the 7:50’s/mile for the short stuff, 8:30-9:00/mile when he went longer. He explained to me that every year he ran the same 5K race and he had hit a plateau. In the 4 years since he started running he had run 23 minutes, 20 minutes and 19:XX twice. I offered to put together a plan for him to maybe help him get to the next level. It was 16 weeks and I set it up like this:
M: Workout. 3-5 minute reps (5K/10K Pace) at a hard effort with jogging rests or 15-20min Moderate/Hard (Threshold Tempo)
T: Build up to 60+ minutes of easy running
W: Easy (He always did exactly 3 miles)
TH: Workout. Quick Fartleks or Hill Reps.
F: Easy (He always did exactly 3 miles)
S: Build up to 90+ minutes of easy running
SU: Easy (He always did exactly 3 miles)
This guy is super OCD. He followed my plan exactly! I kept all the work shorter than I would for someone with more experience. At the start he struggled with workout paces. He always ran the reps too easy and the recovery too hard. After I explained to him that he needed to run the reps a little harder and not worry about the pace on his recoveries the workouts started looking better, but it was clear he had trouble getting anything up to race pace. I figured it was a lack of experience and he wasn’t used to working super hard regularly. Still thought it was probably a decent effort and would help in general.
Anyway, the race came and he ran… 5 seconds faster than last year. A PR sure, but not at all what I had hoped for.
Before this started I thought for sure a person like him who had never done any kind of workout would see a huge boost in his times once he put a plan like this in place, but nothing happened. It was a huge dud.
So what do you think happened? For the general running public are plans and workouts useless? This guy had never done anything then followed a sensible plan to the T and got no results? His average mileage before had been 30-35mpw for 2-3 years and he bumped it up to 40-45mpw for these 3 months. I thought at least the mileage would have a positive impact. Did I waste this guys time? I felt genuinely bad/puzzled after his race.
