Hi Mrs PB. I trained to walk/run the FLM in 2006 - more emphasis on the walking! I got injured but did it anyway - walked most of it. Including stopping to get my blisters dressed 3 times I got round in 6hrs 55. My husband and I raised over £4k between us for Guide Dogs which meant a lot as I have a degenerative eye condition. (Hubby ran it - we passed just as I got over Tower Bridge, had a kiss over the barrier and went our separate ways! He went back to the Hotel, showered and changed while I did another 13 miles!). Like you I kept applying because I wanted to do better. Then I heard that the 5 yr rejection system was being scrapped so I was gobsmacked to get an acceptance mag through the post last week! Downside - I've done no running for a year or so due to persistent niggling calf injury, and I fell off my horse 9 wks ago and landed on my hip - still slightly lame. None the less I've started training - up to a couple of miles with the dog, brisk walking with a very slow trot of a few hundred yards thrown in just to see if I could. So far so good. I'd love to "get round" next year, I'll be 50 on the 12th April and it would be one hell of a way to celebrate being ancient! I'd also like to try to raise some money for St Paul's Eye Unit at Liverpool, because without two corneal transplants done by them I'd have lost my sight. Being sensible, if I'm not up to a minimum of 10 miles by Christmas I'll defer, but I'm sure with steady training, albeit mostly in walk I'll get round in 6 hours or so. Go for it, I am!!
