Triathlete Kristian Blummenfelt is 5'6" / 165 lbs, runs 29:34 10k after swim/bike

He is on Strava so no need to theorize about his running and cycling. He was originally a swimmer, he is great at the bike and he is a beast at going all out in a long finish like he did.

The Norwegian team trains very scientifically and I am sure there is something to learn from it. I guess he runs some 10s/km slower than Jakob Ingebrigtsen on a single 5k which means he is a sub 14 5k runner.

He has been asked about what kind of training he would do if just going for running and he said he would of course max out running milage, keep a fair share of cycling and skip swimming (which does not translate to running). Triathletes are extreme at cross training and are maybe those maxing out on aerobic fitness, together with the cross country skiers maybe. This does not necessarily give the highest running economy which needs to be trained separately.

His running training is as good as any training for 10k and he is not "just running", but of course to threshold and speedwork.

They do crazy amounts of threshold training over the 3 differet sports, but that is possible when being so fit and cross-training.

There is a possibility runners could improve their aerobic base by doing a lot of cycling. Like when running with a low intensity, this will develop your blood vessels and improve their efficiency in terms of blood (oxygen) transport. However, running echonomy is developed only by running alot. Regardless, i think any sub elite runner will see improvements in running by doing low impact activities to increase the volume. The important factor is that it doesn't influence the amount of running volume and the significant workouts meant to increase LT and vVo2max.

In addition, doing hard workouts (vo2max) on bike will increase the vo2max of the athlete. However, this will decrease the utilization rate.

Agree with you. Kristian Blummenfelt felt that a fair share of cycling would give the aerobic base benefit, and he knows and feels this combining cycling and running.

Vo2max is muscle and fibre specific and a number for the capability of the muscle fibre. If you swim, the VO2 max might increase (given you test by using the whole body), but this has no effect for running since you do not use that muscle. The same is probably for fast twitch muscle fibres. They can be trained to use more O2 and contribute to a larger VO2 max, but you do not use it in a longer race and the utilization will go down. Still, I would not mind maxing out on VO2 capability for any muscle.

I have been crosstraining with a bike for some time and at least it makes be stronger in the legs, feeling stronger when running. Have not yet seen an increased running performance though. Need time...

From the other 'fat Norwegian' thread he does high volume 80/20 style training. High volume intervals. All his training is on Strava.

Was a very fast runner as a junior.

An important thing is intensity control and a lot of threshold training at least in cycling and running. For swimming I do not know as load, intensity is very different than for running/cycling.

I presume 80/20 is accurate enough, but not 20% hard, but 20% including a lot of threshold work

We've been here before. Jamin loves this guy:

https://www.letsrun.com/forum/flat_read.php?thread=10087358

He's 177cm, normal average height.

Also just look at photos. He doesn't have to look up when talking to a normal height person. He looks similar in height to those around him.

As a member of the differently abled height club (5'6" and under only need to apply!) you know how to spot other differently abled height folks.

Middle guy, looks same height as guy in front of him. Say, 5'8"-5'9". Some places say 174cm some say 177cm.

Guy trailing looks like Jamin. So 5'4"-5'5".

He himself says 177cm.

The average height in Norway is 181 cm so he is way below average.

He did a 13.51 on a 5k road race last year.

Also did a 3k at the end of an interval session in 8.11

I doubt he's really 165 pounds.

In Norway they use kilograms, and 165 pounds is 75 kg.

71-74 kg guys always round up their weight to the 75 kg threshold.

Just like 5'10 and 5'11 guys in the U.S. always round up to 6 feet lololololol.

Much respect to this athlete and all others who competed against him clean and couldn't win.

Norway is the EPO and blood doping epicenter of the world.

Bersekr genetics favor Norwegians in all sports -- ration of balls to body-weight is highest in world. Many Brits benefitted from this Danesblood as did those down-under, New Zealanders (descendents of Brits)

His open PR 10k is not and will not be under 29.

EPO helps the most. Very little athletic talent except for extreme outliers like Warholm and ingebrigsten in Norway.

In Ethiopia and kenya there are dozens and 100s of high level athletes in every SINGLE event bc they are truly genetically gifted while Norway is pharmaceutically gifted. Painful hard truth!

let us face it, our people are slow, rich cheaters who have unfettered accessed to science and pharmaceuticals.

Henry Rono, Kip Keino were beyond reproach. Why? Because they were poor and their countries were poor.

Paavo Nurmi, like Roger Bannister, was a early

proponent of bull testosterone.
