Hi minn,

I had the same question this summer regarding a December marathon (although I had previously run a 1/2). Well, I'm happy to say that I completed the marathon and learned A LOT from the experience so that when I do it again next year (yes! I still want to do another one!) I'll be better prepared.

Not knowing when your marathon is scheduled, I strongly advise against signing up for anything less than 16 weeks out. In fact, if you can stretch out your training to 18 weeks, all the better. Personally, I agree it might be wise to have a 1/2 or two under your belt BEFORE starting to train for a full, but that is just my opinion.

I used the FIRST method of training, which includes 3 quality (hard) run workouts per week (1 speed interval, 1 tempo, and 1 long run per week). On the off days, you either rest or cross-train (cycling, swimming, yoga, or the like). This worked really well for me and my schedule.

Although I had some mishaps and whatnot, overall I really enjoyed the marathon experience and look forward to doing it again next December.

Let us know what you decide!
