I have been doing 100km and 200km rides previously without power meter.
Now that I have been doing SSLV1 and 2 next will be sustained power build and then Road Century.
I have been trying to figure out what would be the best %FTP to aim when doing these longer brevets now that I have a power meter for outside rides as well.
Lets say 3h up to 12h.
I would love to do these rides without stopping for lunch etc. I will have to stop for filling up my water bottles and if I have a place to get some “service station” where I can fill up my pockets with gels etc. Or then I’ll just carry everything I’ll eat with me.
I don’t have to be fast and don’t plan on racing these on the max effort. Just something I would like do.
My current FTP 221W and hoping to get somewhere around 240-250W
So 50% would get me around 110W. That would make something like 8h 200km according by bikecalculator.com
Could I raise the % to get it done faster or should get it lower to get it done with less gels and more fat from body?
As you can notice I have no idea what %FTP would be sustainable for what time period. So please help me out.
