I’m got a marathon coming up in 3 weeks. Yesterday was meant to be my longest run at 34k but bonked at 24k due to overheating and under fuelling (travelled for work the day before). My current long run schedule has been
8 weeks out - 28k 7 weeks out - 31k (zone 2) 6 weeks out - 10 mile race 5 weeks out - 32k 4 weeks out - 27k 3 weeks out - 24k due to bonking.
Should I aim for another 30/32k next weekend and then taper? This is my first marathon - all weeks I’ve been averaging 30-40mpw with 41 peak. I appreciate anyone’s advice on this.
