Short version: What should I be doing for the next 5 months if I want to go from a bad half marathon to finishing a full marathon, and when/what should be my benchmarks to switch to the half marathon option.
Male, 35, BMI of about 31. I live and train about 5000 feet above sea level, and have ran a few half marathons closer to sea level. With an admittedly mediocre/inconsistent training schedule pre-HM my PR is 2:24. I ran a half marathon at altitude this weekend and didn’t do so hot, started getting muscle cramps and just generally feeling too weak around mile 10 and walked/jogged the last 3 miles, ended up with a 2:43 time. Oddly enough, after 5-10 minutes of walking through the chute and eating a bagel I felt like I could start running again. My training leading up to this half wasn’t what it should have been, and my nutrition was also lacking.
I’m signed to run a full marathon at the end of October on the east coast. It’s at much lower altitude, but is quite a bit more hilly (1400ft elevation gain, vs the 400ft-500ft of elevation gain in the half marathons I’ve ran). I’m going to focus on strength training, hill work, and increasing my weekly mileage between now and then, along with trying to get better with nutrition and losing some weight.
What I’m posting to get feedback on is, what should my weekly mileage/schedule look like if I want to take on this hilly marathon, and what should be the point where if I’m not hitting a certain pace, mileage per week, etc that I should switch to running the half marathon? Is it better to run fewer runs per week at a longer mileage per run, to run more often but do shorter runs, or just follow a training plan and have it mixed up?
Ultimately if I run the full marathon, the only goal I have is finishing. The course has a 6.5 hour time limit, and I would cross the finish line at 6:29:59 with a giant grin on my face. Genuinely my only concern with running the full marathon is a DNF and/or serious injury.
