Ashapalan - I think that 12 months ago I had the same dilemma as you - that of should I or should I not do the FLM? I began my running career (again) at the start of 2005 and did 5 Half Marathons that year. After my 5th Half of the year, a charity that I have supported approached me and asked whether I would run FLM 06 for them. Like you, I was in two minds and I gave it some serious thought for about 2 months, given that it is a serious commitment if you are going to try and prepare for it properly.
I remember posting on RW at the tail end of last year and discussing my dilemma and I think it was Andy from Embsay? replying and urging me strongly that if you get the chance to do the FLM, to go for it because it would be an event that you would never forget. I took that on board and to cut to the chase, I reckoned that I was lucky to be offered a place to take part in one of the best races in the world when there were so many who wanted to do it but couldn't get a place.
I went for it. The training was hard, painful at times but come race day I had one of the best times of my life - probably 2nd only to being at the birth of my two sons!! The whole experience from start to finish was simply incredible. I could never have imagined the atmosphere and level of support that lined the whole course - wall to wall noise - I'll never again underestimate the help that can be gained from a crowd! Even now, just thinking and writing about it, I can feel my pulse quicken and an adrenalin rush!!
I was quite literally on a natural high for two weeks after the race and I'll never ever forget the sensation that I felt as I turned into The Mall. I looked around and thought about all of the times that I had sat watching the event on TV and there I was, not just watching it, but living it!!
So the only advice I would convey to you about your dilemma is if you get the chance - go for it!! Don't put off the dream - live the dream - you won't regret it!!
