In reply to chubbs2:
Having stareted this thread I just wanted to reply for the benefit of anybody else searching on this topic in future. I ran London last weekend as my first marathon and in the end ran a 4:15, following a re-occurence of an on-going calf problem at 6 miles and hitting the wall at about 23 miles. A few lessons learned:
- there is much good advice in this thread from others, especially around not investing too much 'emotional capital' in your first one, especially if achieving your target time is marginal
- get your nutrition right well in advance. Don't try new foods / gels for the first time in the race
- if you get an injury in training, get some good sports physio asap, rather than soldiering on
- for me getting used to the lack of energy around 20 miles plus, would have been better coped with by doing more 20+ mile runs in training rather than the 2 I did. I also think I cut corners on the volume of lower mileage training runs, which I don't think helped with endurance overall
- again if your target time is marginal, in big races, it may be better to ensure you are are at the front of your pace group at the start (or even get into a slightly quicker pace group), to avoid getting bogged down in traffic in the early stages
- if you have only got 4 gels, don't stand next to the 'Billy 10 gels' from Clapham. It will make you feel inadequate.
- if you are running in a group with people in fancy dress, don't run with Spiderman, Wonderwoman and Bananman. It will make you feel inadequate.
Thanks people for all the advice.
