Updates · Running
Below are my latest updates from Mastodon (similar to X, Bluesky, Threads, etc).
Running Shoes 😖 ….
Ordered: 👟 Saucony Endorphin Speed 5 👟
Because: I just discovered that since the 24 hour run in 9 days is an IAU labeled Danish championship event … then it turns out that my beloved 💚 ASICS Superblast 2 💚 are illegal in that context. Because their stack height exceeds 40 mm. Even my Novablasts are illegal. And I don’t dare run in my magicspeed / metaspeed carbon plate variants (they are too tough for the lower legs).
Risky business. Very risky business.
7.5K Run (plus Coros HR update)
I have now been using the Coros HR arm band for the last 3 runs. I feel like it generally has lower measurements than I’ve gotten used to see with my Enduro 3. Today it was an easy run and it measured 126 avg which is consistent with the effort feeling I had cardio wise (disregarding muscle fatigue from yesterday’s session). I will provide a few more updates as to how the Coros experience is 👏🏻🚀
15K Run with Tempo intervals
https://strava.app.link/s7CESf5Rg3b
I recently finished my Runna marathon plan. And I won’t start another plan until after the next 2 races (so in ~4 weeks).
So today I picked a Strava suggested tempo workout. Read: severe threshold work 😅. It was a 4 x 1.5K interval run … with 2 min recovery. I ran them too hard but had fun anyways 😇.
My new Coros HR measurements seems ok responsive and reliable (matches my effort feeling).
And I met my son, also running 🤩
Ordered the Coros HR monitor and expect it to arrive today. It’s the armband type (I’m not super happy with my current Garmin chest strap). Thanks to recommendations from this very network 👏🏻🏃🏻♂️
Background: I suspect my Enduro 3 to be quite unreliable wrt HR accuracy. Some days it’s completely off the radar. Which ofc may be true … but let’s see 😅
8K Run
🏃🏽♀️running now felt easier. I still have a little DOMS - mostly in one of my calves (I think the one that cramped the most at Copenhagen Marathon). Tendon/tissue made itself aware in one of my legs … but got warmed up during the run .. so my bet is that its ok in a few days 🙃🏃🏻♂️😇.
I will for sure not push effort yet 😅
6 months of running daily
I didn’t set out with an intention to run-streak. But I have nevertheless been running everyday since a few days after Kullamannen 100 miles 2025. (For the record: Backyard counted too, but special case🙃)
In general I have since then run a much higher mileage than before it. YTD it’s on average close to 120K per week.
I don’t plan on run streaking. But it just happens these months 😂. 7-8K recovery runs seems sufficient to gear down (taper/recovery).
Regarding why I’m beaten up ⬆️
According to Garmin my effort corresponds to a normal 80K run (easy effort style). I don’t think it is far from it (the feeling here a few days after). But I do think perhaps my BPM rating was a bit excess. Either that or I did actually push harder than normal 😂🧐🤷🏻♂️
(I do find it a little weird that my stamina went to zero after 1h15m ish … that was not at all the effort feeling I had … the entire race did feel manageable. Tough yes. But ok)
The after effect of Copenhagen Marathon is the same as any other ultra run 🤯
Impact on joints … and DOMS even. Here on day 2.
Lesson learned: Marathons are equally tough afterwards (if taken seriously and run “hard”).
✅ Copenhagen Marathon 2026
https://strava.app.link/54zA1hhJ12b
To the point: 3:00:15. I felt great throughout. But at kilometer 39 my legs began cramping. So it put a stopper for the flow. Especially the last kilometer wasn’t very beautiful 🤣. Considering that I’m really proud of the result 🤗🥳.
Best experience for sure: Copenhagen Marathon is super awesome. Highly recommended 🥳🥳
8K Run
Lovely shiny calm morning run. Last one before race day (Copenhagen Marathon) tomorrow 🤠☀️☕️👌🏻. Leaving a bit later towards Copenhagen to check in on a hotel 🏨. Then off to the expo to get the bib and possibly buy something completely unexpected running gear 😅
