This is both the easiest and hardest part of training. Easy in that the longest run left is only 12 miles. The full 18 week training plan includes 562 miles (of which I've missed some due to runs cut short and a handful missed). Only 65 remain to be run. Physically the next few weeks are easy.
What's hard is the mental aspect. Acknowledging that at this point I've gotten as strong and fast as I'm going to get by this race, and that the best thing I can do at this point is continue to trust the training and resist the urge to do more. Recognizing that my original goal of a sub-4:00 finish is probably not realistic unless I have an extraordinary day (now looking for sub-4:15, still a significant PR if I can achieve it). Shaking off the phantom twinges and illnesses that inevitably pop up during race week ("oh my God I sneezed, I bet I have the flu! Is that pain in my ankle?"). Watching the weather and hoping the forecast doesn't call for another ice storm. Channeling the extra energy into planning out my race morning and strategy.
I was lucky to get in a run at all this morning with rain in the forecast all day with at least 60% chance. I didn't expect to be able to get in the full 20 miles given that, but figured I'd get up early, hope for the best, and just keep running till the rain got too heavy or I hit 20, whichever came first. Luckily the rain accommodated me and held off till afternoon.
Good thing, as today was my last best chance to finetune my nutrition strategy. I had gotten some Perpetuem solid tabs I wanted to try (thinking ahead to getting some early practice with them ahead of my next big event) and this was my last chance to try them out pre-marathon. (Verdict? Weird taste and texture, but they sat well and did the job.). Also, I'd had some pain in the ball of my right foot lately which I suspected was tied to my new pair of shoes. That theory proved correct; I ran the first 8 miles in the new shoes and developed the pain then ran home, changed into an old pair, and knocked out the last 12 miles pain-free (RunningWarehouse has the replacement pair en route already).
So here I am, 3 weeks out from the big day. I'm reminded of a quote I saw the other day "medals are just picked up in competition, they're earned in practice." Those medals (this year's and the one I should have earned in 2013), I've already put in the work to earn them. Looking forward to getting out there in 3 weeks and picking them up.
