The signs were there as we drove up the Aosta valley. Heading to La Thuile for the fourth round of the Enduro World Series, you hang a right at Turin and head straight into the heart of the Alps. From the autostrada you can see just a glimpse of the top of Pila, a small hint of the high mountain perfection that you're missing as you scud past at 130km/h. The Pila resort tops out at 2,500m, which would be serious elevation in any other valley - but with Mont Blanc standing guard at the head of the valley at more than twice that height, it doesn't seem such a big deal. Seeing snow at that height at this time of year was the warning sign for what was to come. Sure, the big, dirty snow banks never really melt, but this was a fresh dusting on the hard, cold slate. Fresh snow, in July... Climbing up on the freshly-asphalted roads to La Thuile you could start to see more of the weather that is hanging over the Alps right now, it was clear that this wasn't going to be the endless, hot summer days of the last round in Valloire, the weather was going to make sure everyone remembers how serious big mountain racing can be.
