I too want to do my 1st full marathon next year. I just completed my 1st half marathon (Great north run) and happy with 2.25hrs --I ended up fainting at the finishing line and took out the metal crash barrier and had to go to hospital on a spinal board! Turns out my blood sugar dropped to 1.2! Only me!
Anyway -i now want to train for a full -probably Edinburgh in may? I intend to combine my running (approx 3 mid week runs of about 6 mile and a long one at weekends -getting longer every 2 weeks) with weights and cross trainer.
This is what i did anyway for the half and seemed to work well. Do you think i need follow an actual marathon training programme or carry on with what im doing?
