Trex, sounds like I am as bad as you, cornish will be my 12th mara this year, usually do 4-6, really hate long runs so I just do maras to tick over, its what you do in between that matters i think, cross training, shorter races, I only do 25m on a big week, the only time I go over is when I do a marathon. I was 3.15-3.30ing for the 1st few this year,but the last 5-6 has been between 2.56-3.05 so must be doing something right, (weight loss) i have cut the rubbish miles and put quality running in. also did a 3 min, PB half 2 weeks ago at Stroud 1.20.00 (i know.....dont say it) and that was after doing eden and dartmoor vale maras the 2 previous weeks. so must be doing something right??
As for next year I got Gloucter, Dutchy, Taunton, VLM, shakephere, stockholm, Dartmoor d, North devon, then train a bit for Berlin, well thats the plan. Was looking into galway or longford but flights/ferries are pricey as hell to ireland at the mo. I do fancy that Dingle mara, look forward to hearing about that one!!
