So how does a 1:11 guy get down to 1:09?
Or a 2:28 guy get to 2:18? It seems almost impossible.
Would just bumping mileage from 60-80 to 100-120 work on its own for some people?
Here's my progression.
First, before running any marathons, I ran a couple of seasons of high school cross-country and a couple of seasons of track, mainly the mile, with my best time just under 4:50. In college, I ran three seasons of cross-country and a couple of years of indoor and outdoor track. Indoors, I ran the two-mile, breaking ten minutes twice, and never breaking 9:50. Outdoors, I ran 3 miles, 5000m, 6 miles, and 10,000m. I don't remember my precise times, but I know that I never broke 15:30 for 5000 (or the equivalent time for 3 miles) or 33:00 for 10,000 (or the equivalent for 6 miles). (It's possible that I did not break 34 for 10,000m, but I'm confident that I could do it; I don't want to overstate my mediocrity.) My training varied a lot in high school and college, but even then, I saw that higher mileage resulted in substantial performance increases at distances from two miles to 10,000m; I didn't see similar improvements from programs focused primarily on interval training.
After college, I turned to road racing and, in particular, the marathon. After some months of about 60-70 mpw and regular racing at shorter distances, I ran just under 2:40 in my first marathon. After another year of similar training, I ran my second marathon in 2:33. After adding a second, shorter session of running on most days for a few months, I ran my third marathon in 2:30. At that point, I shifted my focus away from short-term incremental improvement at various distances to more long-term improvement of my aerobic condition as a basis for bigger gains in the marathon, with an eye toward qualifying for the Olympic trials. For about five months, I did no racing at any distance or training at anywhere close to any race pace, and did nothing but mileage of about 100 to perhaps 120 mpw. As I noted in a previous post, the training was not done at what I would consider "easy" paces; rather, it was at paces that were simply slow enough to allow me to handle the increased volume, and those paces would tend to get faster as I adjusted to increased volume. My only high-intensity training was deep-water running, which I added after several months to get through various injuries, but which I felt was also useful as a higher-intensity, lower-impact supplement to "real" running. After about five months of this, I ran a couple of moderate-distance road races, followed by my fourth marathon in 2:23.
Having not yet qualified for the Olympic marathon trials, I returned to my base mileage after that 2:23 marathon. I ran a few shorter races over the next year or so, including a half-marathon in 1:06-low and a sub-30 10k, but some ill-timed injuries and other distractions prevented me from running any marathons prior to the Olympic trials. I then had a period of several years when I focused on non-running stuff (mainly law school) and trained sporadically with just a few races at various distances.
After law school, I returned to the marathon, again training with a focus on volume (mileage). My next marathon was 2:28. After another year of high-mileage training, with almost all of my high-intensity training done in the water or on treadmills (which, particularly at steeper slopes, greatly reduced peak loading forces during high-intensity running), I ran 2:20. Three weeks later, I ran 2:19. After a couple more years of generally high mileage, while continuing to do almost all of my high-intensity training in the water and on treadmills, I ran 2:18. (Because of an impact injury, all of my running for about four weeks immediately prior to that marathon was done on a treadmill at very steep inclines.) As the Olympic trials approached, I decided to take an unpaid leave of absence from my law firm to focus almost exclusively on running for the first time in my life, but I got a metatarsal stress fracture in the months leading up to the trials, and that brought my racing career (such as it was) to an end. (In my forties, I returned to regular training with the hope of qualifying for the Olympic trials again as an old man, but after a year of solid training, I only managed a marathon in the high two-twenties, and could tell that my body could not do what it could when I was thirty.)
My training during my peak years would probably seem ridiculously scattershot to many coaches and athletes, and was certainly unconventional, but it was not mindless, and I believe that I got a lot more out of my body than the great majority of marathoners do when they try to follow cookbook running schedules. I simply learned everything that I could about training methods and the physiology of running, and I sought to apply that knowledge within a variety of constraints. I don't doubt that I could have run some faster marathons if I had been better at avoiding certain injuries or if I had taken different paths outside of running, but that's life. I think it's very important for runners to be clear (to themselves) about what they want to get out of their running and how the sport is going to fit in with the rest of their lives.
