the whw has been done in 11 ish hours one way – typically it seems faster top to bottom. the double in 24 is conceivable but would be very tough. doing it minimally or unsupported would be cool…for those who have never ridden it, some sections are extremely slow and involve significant hike-a-bike. some of it is also PAINFULLY dull.
was it rob lee who popularised the concept of doubling long distance walking paths? something to do with the south downs way? whatever, its simply an abstract concept that seems to have stuck. Rob had a well publicised attempt ( i met his support crew that day as i passed by doing part of the ‘way but i was heading east over ben lomond – again, they were very organised ) Shaggy attempted it in insanely bad conditions a couple years ago and aidan harding has had a couple goes as well both with little or no support and both have been thwarted by mechanical and sheep collision issues iirc.
The terrain is often very rocky and unforgiving…nothing too dramatic but cumulatively, with added tiredness, a significant undertaking. If you know it well it holds nothing to fear but you need to have your game face on for sure…the south downs it is not. rich rothwell was on-sighting part of the route – and imo a significant part. the support was delayed and this seemed to lead to issues.
Good on the guy for achieving a first…my preferences are more for the ‘alpine’ style (disaster style?) approach, but that is personal.
