I’ve been both a supporter and a supportee - it’s hard to say which is the most fun or which is the most tiring.
I second what has been said about people coming up after being supported, it’s an incredible sight that you miss out on when actually doing the thing.
There are elite runner, fast runners, wheelchair “runners”, average runners, and the real heroes those who are going to be on their feet putting in the max effort they have for up to 8 hours or more. Those people need this support station more than anyone else, if only for the fact that people stay and are encouraging and cajoling (and occasionally abusing in a Barleyesque fashion), those exhausted determined people.
So come on people, if you are not running, go to Mudchute and taste what marathons are really all about
