Hi all,
long time lurker here. I’ve discovered the forum about half a year back. After reading through the 10k+ posts I thought: might as well give it a try and in a later stadium add my experiences.
Background
Over the past few years, I’ve been a very effective boom-and-buster. I have been running on and off for over 7 years, usually running about 6 months of the year, taking the rest off due to injury or burn-out. Looking back I’ve averaged about 20km/week/year since 2021. With peaks around 70km/week during marathon build-up and absolute lows where I wouldn’t run for weeks on end. Furthermore, usually I’d run my easy runs around 150 bpm (HrMAX = 187) and beat myself up at the track weekly whenever I wasn’t injured. Had a lot of fun, and some linear progress. Since 2022 I started cross-training with cycling and swimming for a total of 6 hours, that increased to 8 hours in 2025.
Some PRs from recent years:
2022: FM 3:00, HM 1:24, 10k 37:xx, 5k 17:40
2023: FM 2:56, HM 1:21, 10k 36:30, 5k 17:10
2024: HM 1:20, 10k 35:30, 5k 17:04
2025: 5k 16:48 (March), 10k 35:30 (October)
Through this I’ve gotten seriously injured every half year, peaking in 2025 where I
made quite a jump in my 5k time in March, but now had structural nags and pains
during the rest of the year.
NSM
Stumbled upon NSM in September, started reading the forum and figured I’d give it a go. Decided to take 25k/week as a starting point and take my time building up from 3 to 4
times a week. I ran only easy (now being <130 HR for me). Which was incredibly slow, starting around 6:00 min/km. Took a while to get used to. Collected a lot of street credit by chatting with the elderly who I was now running along with. Quite relaxing. End of October ran a 10k race as a starting point in 35:30.
In November I started adding sub-treshold intervals, as I had now reached 5 weekly runs in
a sustainable manner. Built it up by a few minutes each week, reaching about 45-50 minutes over three sessions in January. In the meantime my easy pace dropped from 6:00 in October, to 5:50 in November, to 5:45 in December, and a big jump to 5:30 in January.
Last weekend I ran a 34:09 10k, on the same race where I ran the 35:30 in 2025. Felt quite easy, never even came near those paces during training. Yet still, big PR. And no injury. Very happy with this result as it didn’t feel like a peak performance at all. I’m intending to stick to 5 times a week as that is sustainable for me, not going to build above 25% of volume for sub-treshold. Going to try a 5k in a month or two.
In my opinion the biggest success is consecutively running 50k weeks for several months now, without injury or feeling burnt out. I have never done that before and am enjoying it thoroughly. I realize that I’m only applying a stripped down version of vanilla NSM for
cross-training, plus I’ve only been doing it for a very brief period of time relative to others. However my experience doing this is so much more positive than any other running method so far that it doesn’t feel premature to share a good result in this stadium.
Anyways, will post another update when I do that 5k some time in the future.
Kind regards
