Weather forecast was 31 degrees so i started earlier than planned with the aim to get up Elidair Fawr before it got too hot. I weighed up a couple of hours in the dark vs extra time in the heat - on reflection this was a very good decision.
Water was the biggest challenge, I carried 3 x 500ml bottles (2 full at the start) and a filter flask. Pen Y Pas tap was off (they have E-Coli again!) so I missed out on getting a top up until I was able to filter some water, which was a bit iffy from some of the places I filled from (even with a filter) so I wasn't drinking as much as I wanted to and in the last 20km, apart from Llyn y Cwn there wasn't any water to be found on the hill.
The second half was super hot and being quite dehydrated impacted my ability to move quickly (as did the boulders on the Glyderau!)
Gorgeous route though and I had such a nice day out. Apart from the heat, the conditions were great - apart from the usual bogs the running was fast and dry and stunning views and a "Buck moon" over night in my honour ;-)
