Sorry but my Mum won't let me talk to crazy people!!!
Seriously, I guess it's gotta be loads of carbs in that hour or so after the first race. Maybe start with a sports drink and then get stuck into pasta etc. Also, if you can, try to get into a COLD bath as soon as you can after the first race. I understand that this will help with the muscle soreness that you're bound to get.
A massage would be good too.
Good luck you loony!!!
All the best,
