I wrote about the effect of weight in the Norseman bike course a short while ago. In the comments someone mentioned some like; «sure, now I just got to lose 10 kg and increase my FTP by 50 %». While irony is impossible to read I could sense a bit of it in that sentence. Then it struck me, my number is relevant for about 10 people competing in Norseman. But what about «Average Joe», how does weight affect him? With the BestBikeSplit-analyzing software, I did some calculations.
The difference in bike strength in Norseman is huge. My Average Joe was given the following stats:
- Weight – 80 kg
- FTP – 240 watts
- Bike – road bike with aerobars (average CdA of 0,37)
The estimated bike time with the most likely weather would then be 7:00:00.
If we put on more weight you could see the added time would be as follows
- 1 kg + 2 min and 8 sec
- 2 kg + 4 min and 16 sec
- 10 kg + 21 min and 41sec
In comparison my time penalty of weight was:
- 1 kg + 1 min and 25 sec
- 2 kg + 2 min and 51 sec
- 10 kg + 13 min and 17 sec
In other terms. The negative effect added weight for Average Joe is about 50 % higher compared to an elite athlete. The world has never been fair, right?
If this changes anything regarding my advice to use your money on unpaid time off work in order to train/recover better? I will say no. Staying in your best shape is still the best investment you can do. Choosing weight before aerodynamics? No. Aerodynamic gains are more time-saving in the not so fast triathletes so they have even more to gain than my calculations in the previous post.
Then again, I hope this post put things in perspective. A slightly more precise and relevant perspective 😉
