I will tell you were I am and what I will do......
I have been running approx 50 to 60 miles a week (average) for the last 4 years or so. Ran 17 marathons and 1 ultra last year (ultra was a double marathon). The only "special" training for the double-marathon was back to back long runs (Sat/Sun) of 13 miles each day 5 weeks before, 15 miles each day 4 weeks before and 20 miles each day 3 weeks before. Got around in under 8.30 very comfortably.
Ran 2 marathons on consecutive days last Nov (a track marathon the Saturday in about 3.50 and the Rutland Water marathon on the Sunday in about 3.45).
I had no injuries, no DOMS from either event but went with the sole intention of competing the events with time being very secondary.
Personally, I believe that once you get X amount of training/miles/racing in your legs and maintain a "basic" level of fitness you can pretty much turn your hand to anything that is similar without needing to ramp up the training.
Obviously, "racing" the event over 4 days would be a different kettle of fish to just "getting around" and enjoy the experience.
My last spring marathon with the South Downs in June (8th marathon of the year) and then a gap until early Sep where I will run 3 or 4 (on consectuive Sunday's) before the Great Barrow event. I don't plan to do any back to back long runs at all.
This is going to be my approach based upon what I have previously achieved. I doubt it will work for everyone and may not work even for me
Sometimes less can be more!
What are running in June? South Downs? Boddington?
