I'm a bit concerned at the pace of doing by long runs. I seem to run them quite naturally at about 8-8.10 for a distance of 18 miles. It's hard, but after a shower and something to eat, I could most probably go back out and do a few more miles, so I'm not exhausted by it. But is this too fast for a long slow run for a 3.30 marathon.
All the schedules I've looked at say I should run these runs at about 8.52 pace, based on my last 10k time earlier this month.
Also, I normally do a long run every week leading up to the marathon unless I'm racing, but again the schedules say not to, do them on alternative weeks.
I do not want to become over trained as this time I'm doing 16 weeks of training as opposed to only 12 & 14 in my last 3 marathons. I've decided on more weeks to try to achieve subb 3.30.
I've worked out my plan, by adapting several to suit me, but I'm starting to question if I've set up too hard a plan. Remember I'm regularly running 30-40 miles a week with long runs up to 16 miles even when not marathon training.
I know this is a long post but honest all advice appreciated and accepted.
Over 16 weeks my plan is for only 4 days of running based on tempo, speed, long and easy, one swim session and one circuit session, with one complete day of rest. Long runs go like this:
18,20,10 mile race,18,16,1/2m race,21,10 mile race,22,18,20,15,23,15,10,marathon. Highest mileage reaches 60 miles on week 13, which is still not as much as 3xlong run.
Thanks in advance. Hope you haven't gone to sleep!
