Did my first 3peaks last year and I’m in again this year.
I’m not a fan of Camelbaks but after some experimenting that’s what I went with last year and I’ll do the same again this time round. Figured that with no-one to hand me bottles, the fear of losing one would be significant, plus the cages would interfere with shouldering the bike. You’re carrying the bike a fair bit, its worth making it comfortable.
Got the smallest Camelbak I could find, half-filled the bladder with an apple juice/water mix and was able to squeeze in the emergency blanket thing, 2 inner tubes, pump and minimal toolkit without it being bulky. Bit of food and gels in jersey pockets, pipe lagging on the top tube near the junction with the seat tube and it was fine. Stashed a bottle of isotonic drink behind a wall near the foot of Penyghent which I retrieved and guzzled as I started the climb. I’ll do pretty much the same thing this year I reckon, probably get the kids to hand me the final bottle as we’re staying in Horton this time.
