| Comment | I guess if you're planning to walk a good proportion of it, that's fine, but if you want to run it - the issue with that kind of event isn't fitness or stamina, it's glycogen management.
You're going to be doing the calorific equivalent of 40 miles on the flat, and until you've run extensively beyond the 20/25 mile barrier it's hard to gauge how your body will react. Running it is about equivalent to twice that distance/height in hiking. In a traditional marathon if you get in trouble you can just walk it in, but in something like the Glencoe race you could be suffering quite a way and do yourself some actual harm.
I'm not doubting your capability to do it, but it is pretty much getting into ultra territory, and I'm just surprised anyone would go straight to that without a normal marathon as a self-assessment. |
