What to do or take to get prepared for a charity cycling race coming up in two days

Ok first off always what I use is one bottle of water, tissue oils for mussles if you do get cramps, there is also the frucose < Which is made out of fruit, I believe... Its a package that is like surup... Get yourself a shirt that can get air into it. That's all I know... There will be medics I believe if not wish I was there then, becuase I use to hlp my family out at the "Voet van Afrika"
