I say bring it on bitch!
My challenge will be thusly:
12 bets, at 12 different sets of odds.
1/12, 1/11, 1/10 etc etc, which should hopefully all culminate in a £325 bet at 1/1(evens) as the final bet. In the spirit of Xmas, if it all goes swimmingly and all 12 win, I'll bank £250, keep £200 for another RTR try, and chuck the other £200 to charity.
I'll try and make the bets in order(ie starting with 1/12, then 1/11 and so on) but it might pan out differently.
