@Alan_Couzens I didn't even know you can do that!? kudos to this decision.

Andechs Expert Trail Race, 16km, 500hm, 1:30h, happy. this was a training race for a bigger one in a week. running last meters with our little ones. and they had as much fun as I. ended up midfield. 25/57 of my age group.

Running >70k a week, strength training, fueling, recovery - All of that working full time + taking care of fam w young kids.

Being a part-time endurance athlete is all about time management and I used to suck at it.

7 principles I learned over the last year to make it work:

[Thomas Hertz @primtom]

@johngetstrong @johngetstrong , you said you increased your running mileage to 50km/week. was this the only aerobic training you did, or did you complement with e.g. indoor ergometer/bike?

[Thomas Hertz @primtom]

@Alan_Couzens @Alan_Couzens , do you have any thoughts on @LumenMetabolism for testing/checking your metabolism?

[Thomas Hertz @primtom]

@RndmForestRunnr @TheSpineRace all the best! cheering for you!

[Thomas Hertz @primtom]

@MauroneBad @Alan_Couzens i would have the same question.. 8h standing instead of sitting.. how much does this offset..

Snow is back here. Went for a lovely run through winter wonderland. https://t.co/sGYTHUcGSk #strava

My year in running! a map representation of all my runs in 2023. more than 200, in average more than 10km. a solid year, given i added also cycling to my training mix.
in yellow my three bigger races: Hohe Winde Bergmarathon 45k, Zugspitz Ultra 90k and Wildstrubel by UTMB, 55k. All finished, no injuries. Lets build on that.
for 2024 i'll closely watching advises from @Alan_Couzens and incorporate those into my training.

A favorite way of putting strong #FatBurning into a context that is very relatable - power on the bike...

Medium metabolic fitness =
Fat powers everyday tasks
A relatively metabolically fit individual with fat burning of 5kcal/min can generate about 83 watts purely from their (almost infinite) fat stores. As you probably know, this is a "walk the bike" intensity - enough to tootle around on the flat at very easy intensities &/or move through the non-training part of your day.

Strong metabolic fitness =
Fat powers easy training!
A very metabolically fit individual, e.g. a professional Ironman athlete can double this & generate ~170W purely from their near infinite fat stores. Throw a little exogenous CHO in the mix and the athlete can actually replenish glycogen while still doing some good aerobic base work!

Poor metabolic fitness =
Fat powers nothing!
A metabolically unfit/unhealthy individual is typically 4 times lower than our elite Ironman - able to power only ~40W from fat! 40 watts won't get you very far, very fast. A walk to the mailbox will have you over that! Which means, our metabolically unfit individual is dipping into their precious glycogen stores for many tasks through the day. This has a massive negative effect on their recovery and tolerance to training!

This is what building that strong #MetabolicBase is all about!

@lupinrider @Alan_Couzens it's not for me..never saw that with your posts.

[Thomas Hertz @primtom]

@jameybilyeu @Alan_Couzens love this response.. :-) to not hit the next root or stone.. narrow focus.. but for running healthy over trails in two years, probably zooming out makes sense ;-)

[Thomas Hertz @primtom]

@UltraRunnerPod @Strava before we add sports this, i'd vote for getting very common sports like basketball in first :-)

[Thomas Hertz @primtom]

@DarkasKc @Lord_NicolasX aber du folgst @arminia bielefeld . nur wegen 'normaler mensch' mein ich 🤣

[Thomas Hertz @primtom]
