My VO2max plummeted downwards as part of the Ultra prep-training. Because almost 50% training / races failed or got canceled (mostly due to accidents or sickness or work…) in the last 8 weeks. And in the last three weeks of May, I gained 4 kg weight. Junkfood and beer !!! And its not over untill after Copenhell 😁 Copenhell is beer and junkfood, and beer ! 😜 So most likely tomorrow is going to be a short run – less intense – and then nothing until saturday. Bodyweight in terms of fat on the stomach, has a huge impact on my running performance. The same weight gain from upperbody muscle training does not impact my running at all. It actually makes my 10K's and higher distances better.
