I posted this in the marathon forum but no one has answered—perhaps someone in this group has some insight?
I am currently using the 16 week half marathon program for a race May 26. First two weeks of July I’m going on a two week hike, the Tour du Mont Blanc, which will be 7-10 miles a day of ascents and descents, so I will need to break in my boots and train for that in June. I’m signed up for my first marathon October 6. I want to use the chi running training program, but when I return I’ll only have 12 weeks to train, not 20. Given how much I’ve been training, and that I will still be training, just working in hiking (only 2 weeks will be run-free 100% hiking) do you think it will be doable to start the marathon program midway through? What week would you suggest I begin on when I get back, and would you recommend skipping particular weeks to get back on schedule with long runs and speed work?
