I’m actually not sure what Dev is saying, but I would seriously caution if you haven’t run marathons before, making the jump from half marathon to full marathon is NOT an easy one. It’s multiple fold harder than, for example, making the jump from a 10k to a half marathon.
I’ve done 6 half ironmans, and none of them have compared in difficulty to racing a full marathon (this was when I was a pure marathoner, NOT as a triathlete trying to run a full marathon a la Gwen Jorgeson.) The pounding of 26.2 at open race pace is simply unparalleled compared to HIM.
I’d say if you can get your weekend long run up to 22 miles, you’ll have a good sense of what’s in store for you. Ignore all the online posters and plans who say you can get away with 15 milers or even 17 mile long runs - you’re not an experienced marathoner, so you need to push that distance to get a realistic sense of what kind of suffering you’re going to be in for. Do that 22 miler two or three times, and you’ll actually be very well prepared for the marathon.
I can complete HIMs at a decent clip even with half-baked training, and still do ok compared to my ‘in-shape’ condition, and without too much agony. Def not true for the marathon. 26.2 miles of running is a whole different level of specificity and training if you’re racing it and not just finishing it.
Maybe you did not read what I said. Anyone who can run 13 miles can run 21 miles and get through it. The problem is always the last 5-6 miles. What is the best way to get physiologically adapted to it? Well it’s not doing weekly 22 mile runs and then sitting around most of the next week trashed and sore and having to take time off and then week over week carrying niggling injuries. 22 mile long run if you’re a Kenyan and getting it done in 1:50 “jogging around”. It’s even fine for your 2:40 guy getting it done in around 2:20. Once you get a lot slower, best to restrict long run by time and figure out ways to physiologically adapt to the race day stress without breaking the body on next weekend’s training.
What I am telling him is not to worry about single long runs. What is more important is weekly mileage. Let’s take 2 runners. One guy does a 22 mile long run and three other runs of 6-7 miles for a total of 40 miles. Another does a long run of 10 miles but much faster and 5-6 other runs of 4-8 miles also run much faster than the first guy. I’m betting on the second guy to have a better marathon.Throw in one week where the longer run is 16-18 miles and that should be plenty if that person is also walking 4+ hours per week on top of this and maybe throwing in some water running. What AK crafty said about getting on a treadmill and power hiking at 15% grade is a much better compliment to running than the elliptical too, but careful with that on the calf and push off perhaps doing some power hiking also at 0 percent grade every few minutes to give the calves and achilles a break
I actually disagree pretty strongly the recommendation that most newb marathoners not run 20 milers and just do 15 or even less for the long run (but faster).
I can say with certainty that if you’ve never done the 20+ miler long runs, and only have ran up to 15 miles at a time, you’re gonna have a really, really rough time of it on race day, and dramatically underperform. I’ve done this exact training regiment myself, with 40mpw and 15mpw max long runs. In fact, it was the total failure of this type of regimen for me that pushed me toward the Pfitz bigger-mileage programs.
I do think the equation is different if you’ve done that 20+miler training in the past and/or have run a bunch of marathons. I’m fairly certain there’s some sort of long-term physiologic change in the legs that occurs when you’ve done it, such that it retains that endurance capability for much longer, and thus you can get away with a lot less in the future. Much like a super fast ex-swimmer can their FFFOP speed back with shockingly low yardage whereas a beginner with otherwise good potential might have to swim 20k+ per week just to become a barely FOMOP swimmer because they haven’t done it before.
The one thing the 20+ miler does for sure that is crucial for newbs like the OP, is that it’s usually a rude awakening to how unprepared you are, physically and mentally, to RACE the 26.2. It’s a crucial step for beginners who aren’t gifted runners to at least do one or more of those long runs. I’m also certain that for newbs to the distance, you get a lot of physiological changes that your body just doesn’t do at 15 miles if you’ve never done 20+ before.
But I feel very strongly that if you’re new to marathon racing and training, if you haven’t yet run the 20+mile training run ever, you will almost certainly get a really rude awakening at mile 22 on race day, even if you’ve been putting in your 40mpw, fairly fast.
Did you even read that he plans to run in early Nov? He does not have time to cram in long runs and recover in time. Better to save the long run for race and ffocus on mileage-time on ffeet and adaptions…did. you also walk 4. Hrs per week?
