IMHO: That is a very dangerous stunt to try out. I have been riding and commuting all my life and I certainly could not even come close to completing that in one day. I believe it will cause many injuries like saddle sore cysts, strained muscles, over exersion etc. A very well trained professional athlete could do that on professional super light weight road bikes only. The average every day cyclist may be able to do it in 2 days with the proper equipment but certainly no mountain or commuter bikes.
