05, 06 and 07 had moments of utter misery
06 people got sunstroke chap! I only did 2 laps, as a stand in for someone who was really ill (sunstroke), and was VERY VERY red myself come Monday morning and back to work.
2010 was so dry I did the whole thing on a pair of 90s vintage green Michelin file-treads.
2010 was lovely conditions, not too hot, but nice and dry. Shame I got drafted into a team of really quick guys as they lost someone with a few days to go, and ironically I was the next fastest person they knew! I very nearly killed myself trying not to let them down... Still, 21st out of 132 iirc in category, that's about the highest up a field of entries I'm ever going to come in my lifetime.
Got to agree with this, unless it's a full mud fest. Last year I did one lap in 1.8 Medusas, then changed to 2.1 crossmarks for the rest of the time, much much better!
I think the mud clearance is more important than the tread itself. Hence why the old 1.5" conti XC's seem to be so good, and CX tyres for the 29ers. Not heavy treads, just thin and still very fast. Thinking if it's horrid I'll fit the narrowest tyres I can to my full sus bike, as ironically it's got quite a bit more tyre clearance than my HT (though the Maverick DUC32 fork helps there!) and just slice through the mud with 60psi in some 2" tyres or thinner. Preferably still with not too much tread though, so they're still quick.
