@ Lyle:"... Had you really never run more than 13 miles ever, prior to your first marathon? That's a pretty big jump. Did you end up walking? What did you learn about yourself as a result of that jump?..."
Yup.... 13.1 is the most I had ever run, once in May 09 (my first half-marathon), and in September 09 (my second half-marathon). In between I ran twice a week during the week 2miles, a 6-8mile over the weekends, and also did (2)5ks, (2)10ks competitively. Starting July 09 I started commuting to work on my bike, which from September 09 to March 10 was my only way of 'exercising'. March-April I was mostly injured, in crutches, and convalescing on my knee (open it up, got 6 stitches), but was able to get back on my bike after 2-weeks with caution... running wasn't possible, but biking was less impact on my injured knee and good therapy. I didn't want to mess it up, so that's why I only did (1) 8mile run until the weekend before the marathon as a test, and felt good, but hurting on my atrophy-leg. So I got some high-performance capris from CX-W to help my muscle-atrophy leg... and I did it.
I only walked twice for a couple of minutes, but proved to be painful -pushing/running/jogging was better. From Mile 0 to mile 20 I was rather comfy and just generally aching as time went by, from mile 20 to mile 24 my atrophy-right leg was aching pretty bad, from mile 24 to 25.8 I was in real pain and slowing down, but pulled through, and sprinted the last half-mile.
Finish time 5hr: 10min: 06sec. I was running with a buddy, so we stopped 3-times for bathroom breaks which took a total of 15 min. from our time.. so, yeah. Less than 5 hrs.
At the end yes, I was hurting overall; mostly my right-atrophy leg, then both feet, then my healing knee. I did have difficulty walking for the first 2-hours, but I took a 1/2hr 'freezing' bath on my legs to detox the acidosis from my leg muscles, and afterwards -I swear! I was dancing at the after-marathon-party..... and that was it. I waited (3) days to get back on my bike, and did had some overall soreness that only lasted a week or so.
Was I wise? Nope -bad, bad....... my doctor didn't think I should do it, but after seriously training for a year, I could NOT not do it. I listened to my body and kept pace as it felt comfortable, and most important.... had ALOT of fun! Except for the last (2) miles or so, I enjoyed every minute of it...
What did I learn about my jump? Well.... seriously, that I'm lucky. That while it is a real physical struggle, your mind and perseverance play a huge part on what you achieve. That listening to one's body is key. And that it would have been easier/less painful at the end, had I hadn't had my bike-knee accident.
So... once again, I'm trying to not run out-of-luck and prepare for my next challenge, which now it has become reaching my 'century' during this summer.
Also.... here on the forum someone posted Radiolab's podcast titled 'Limits"... I listened to it some days before the marathon, and it was a great inspiration.
