Ok all you gadget heads out there I am trying to get an approximation of how many watts I would need to put out to ride a flat course 40km TT in under an hour. In fact the fastest 40km I have ever clocked was for the first 40k of a Ironman bike split. Quite how he knew that after riding in front of me for 5 mins then dropping me like a hot rock, riding an extra 10 km, fixing two flat tubulars and then only trailing me home by a couple of mins⦠I am not quiet sure but I was willing to take his word for it in order to cheer myself up.
If you can go in the first hour of a bike split you can definently go under 1 hour for 40k. You have the aerobic capacity, maybe you just need some more threshold training. It all depends on how aerodynamic you are on the bike.
Have you seen www. None of the trainers were very accurate, and frequently power would be completely different when i tested my SRM or PT against several units of the same model e.
So it could be a bit off, specially the older one that you cannot calibrate. Also, bear in mind that I have just estimated your frontal area and how rough the road isβ¦ Only one thing I can sayβ¦you have too many toys! I have a Taxc trainer that reads out power as well. My reluctant conclusion is that it is pretty much useless. I also suspect that the wattage figures vary depending on how well warmed up it is, and possibly other factors as well, i.
Last week I was doing 5 minute intervals watts. This week I switched my rear tire, and tried to adjust the roller tension to get the same amount of spin down time at a given speed as on the old tire. So yesterday I could only manage watts for the same set of 5-minute intervals. Were my legs dead this week? Or, more likely, the wattage figures shown had no relationship to reality? Who knows which is right?
