In the High Peak Marathon my team mates, who I didn't know from Adam until I got there, were carrying huge backpacks and carrying a ton of stuff including food and bladders full of liquid and all sorts. My pack was a 10 litre jobbie whilst they all had what looked like 25 litre bags. Needless to say they were carrying far far too much stuff (and they were also not nearly fit enough for the event but that's another story). Two of them also had mixed nuun tablets with their water and found that a) it made them feel sick and b) was almost undrinkable because of that. So not only were they humping bladders full of liquid but they didn't want to drink it either. All the extra weight didn't exactly help with their lack of fitness either! Doh!
You do go from the sublime to the ridiculous with your HPM teams! Seems to me a testimony to the quality of the event itself that you persist.
