Could be shortened hamstrings? I have run several marathon, but didn't do one for about 2 years (or anywhere near the same amount of training) and in that time started cycling. When I trained for a marathon at the start of this year, I had a few problems and one of them sounds like what you have. I think proper stretching is the key, especially if you cycle too because the leg movement is different from that of your natural running style and coming off the bike the hams will have contracted and be tighter. I've also heard joga is good for runners' suppleness and flexibility, but never tried myself. I'd go with some extended hamstring and calf stretches. There's a stretching 'bible' by Bob Anderson, which is a great book.
