OK you guys talked me into it. I told work to go stuff it and I'm going to be crew chief for Steve the VT 100. Any crewing tips or links?
You have your priorities right!
There are no doubt plenty of reports on the web for trawl for info. From my experience, the runner should give the crew a list of what to have ready at each aid station - bottle(s) of sports drink ready, number of energy gels, other food, change of shirt/socks/shoes, etc.
There is a deli where you can buy ice and water while heading to the first aid station where you will see your runner. Bring a cooler and fill it with ice, will keep food and water cool.
folding chairs - for crew mainly, and for the runner if they need to change shoes/socks or just to have a rest. The crew does a LOT of sitting around so might as well be comfortable.
Basin - fill it with water to wash feet, this is so refreshing.
Changes of clothes - sweaty clothes chafe so it is good to put on clean ones every so often. It may get chilly at night even in July so be prepared with warmer stuff.
Headlamp and batteries! Unless he is so fast that he will finish before nightfall.
