I am taking part in a 24 hour run, in July, as a pair. I have been running for a number of years having taken part in races from 5k up to marathon and train 3-4 times a week. When training for a race I like to follow a training schedule but just can not find one that fit's the purpose. I was wondering whether to follow a marathon training schedule but split the long weekend runs into a morning run and afternoon run. Any advice would be most welcome. Thank you.
