The Sw100 does look an epic route, but honest thoughts on whether it's do'able as a first 100 miler. I've done a 50 miler, lots of trail running, and like harder rather than easier, but 100 is new territory for me, and not sure of i'd be biting off more than I could chew
It's on my doorstep as well so I would be training on the course with most of my runs.
Yep, did it in 2014, it's a toughie.
Swim, no real issues, a bit weedy in places
Bike, cracking descent, nice loop around South of Brecon, bitch of climb back up through Llangynidr
Run, 3 loops, 1st half flat, 2nd half lumpy
Not a PB course but a great little event
