I also did the track marathon the day before, think I did 4.20 ish then struggled around Rutland in just over 5 Hours
I dont remember a good goody bag either, maybe speedy defines good goody bag differently to others., to me a good goody bag is food, drink, no leaflets and maybe a few shower gel a d deodorant samples, dont remember any of that
The thing I didnt like about this Marathon ws the long walk to the start in the freezing cold in your race kit
