I’ve finally come up with the outline of a plan!
My aim is to complete the event comfortably within the cutoff time; I think my speed is already OK for that so I don’t intend to do much speed work (although I might do some on Wednesdays). Plan is to walk up the hills, walk down the steeper ones then either run or run/walk the rest (I’ll decide on that based on how my training goes).
It’s basically a merge of a couple of published plans with my existing routine. I think it keeps to the 10% rule except for the 50k training run and the race itself (some of the early weeks might look like they break that but I’ve recently had a 61k week with a 42k run so I should be OK there). I’ve included three rest days each week, two on consecutive days. Every other week is a cutback week because that’s what I’m used to. Cross training still needs to be added in.
Any comments gratefully encouraged!
