Beautiful running form during those tests Ben, you looked incredibly strong. You are going to absolutely smash Valencia, there's no doubt!

Seems like a great lab, but i need to say that i think (and this is my opinion as a sports scientist) those results will not represent your actual fitness. The stages are too short for sub-elite/elite runners. you'll experience, that your aerobic and anaerobic threshold are lower when you do a lab testing with longer stages (2000m stages) or a field test with at least 1200m stages. What I find really frustrating, is, that they still use a 2 mmol and 4 mmol blood lactate value to determine your aerobic/anaerobic threshold. Those are very individual (e.g., mine are 0.75 mmol and 2.2 mmol). So, usually they should have individualized the results and dont just put them in a sheet to search out the 2 mmol and 4 mmol...when i first saw your results i thought it would be around 1,0 and 2,5 which would be way more accurate. I just have put the results inty my software (we are using the Dickhuth principle from 1988, they are using Mader from 1980) and in my software your results would be an LT 1 of 0,9 mmol, BPM 161 and km/h of 16,2 and a LT2 of 2,7 mmol, BPM 182 and km/h of 19,9 which i think are more accurate

3:25 Pace: „so before the test really wraps up and the eget to the high Intensities“ you just called me slow in 20 different languages 😭

What sends the report a little out of whack (optimistic on threshold speeds) is using 2mmol and 4mmol for LT1 and LT2. It should done visually by inspecting the curve. LT2 at your inflection point looks just below 19kph. Which would marry presumably with you currently being in 67min(ish) half shape.

I'm a bit puzzled by fact individuals with expertise are going off arbitrary nominal values of 2 and 4 instead of looking curve and where it starts to rise (LT1) and roughly where's the inflection point (LT2) where it goes exponentially.

Source: No expertise in sports philosophy (so ignore me) but I am government analyst (so I like looking at data).

Also for completeness your LT1 point is a little harder to judge but seems at 16.5k-17kph.

So what I'm saying is I believe testing protocol and results collection to be accurate but don't agree with final interpretation of said results.

Great video as always, and in another life I with I had gone into sports testing field.

That last pace of 2.35 minutes per Km that Ben withstood for 'only' 90 secs is the pace of Cheptegei's 5000m world record 😂

Yours is such a tiny window from LT1 & LT2 in terms of pace.
Your strava states your threshold between 3:04 to 3:17 (This test 2:47 to 3:06)
Also, endurance/tempo on strava 3:17 to 3:39 (this test 3:07 to 3:31)

Love how honest this video is and how much data you share, many people would not share their lab results! Hence these are super valuable insights, thanks ben

22:57 The absolute peak oxygen uptake is divided by your bodyweight to give the relative peak oxygen uptake (commonly referred to as VO2_max). This is reflected in the dimensions of each quantity: [Absolute peak oxygen uptake] = L^3·T^-1; [relative peak oxygen uptake] = L^3·T^-1·M^-1. The relative value can be compared between athletes of different weights to see which can consume more oxygen relative to their own weight. It also reflects that an athlete can improve their aerobic performance by, all else staying equal, increasing their absolute peak oxygen uptake (aerobic training) or by reducing their bodyweight.

great work ben im hoping to smash my pb at parkrun this weekend 😂

Great video mate! It's awesome to see the data and the impact this will have on your training. Excited to see what your progress is like through to Valencia!

Great video looks like a very worthwhile thing to do

You can do it Ben! God Bless !. Thank you for your amazing and informative contents!

Really good video Ben, enjoyed it and lots of good data in there. Having done a vo2 test myself I can relate to it, but your numbers are way better than mine 😂😂

Really interesting stuff. Great vid Ben! 😀

Really great insight into what lab testing looks like. Thanks Ben!

You know you are cooked when there is a solid few seconds before the Garmin reflex turns on!- Good job pushing it to the max

Am excited for you Ben. Taking your foot off the pedal in Berlin, was the best thing to do to save you for Valencia.  Make sure you continue your strength and stability training too.  Onwards and upwards 🙌 🎉

Great explanations-thanks for sharing

Haha. There is no way I would go through all this unless I was a world class athlete.

Ugh! I can’t wait to get back into running! Love the content Ben!
