Nicole, as I remember the drink stations are every 5k, can't think for one moment hydration packs would be banned in Valencia.
Just completed my first 100 miler and into the second week of two weeks off training, climbing the walls. Marathon training to start in earnest on 1st September, desperate to get the four hour monkey off my back.
An interesting turn of events, Tom! The low trees and hedges were definitely real..
The section of the course from mile 60 onward was a bit special in a weird sort of way. Still feeling semi alive and no real pain of significance, through the woods, enveloped in complete darkness, this carried on for miles, not experienced such a tranquil environment for years/ if ever.
