Steve_b77 – some more tips for you, and others:
Tyres: 75 – 85 psi with heavy/touring inner tubes
Gears: aim for a 1:1 ratio, but 34 x 30 should be OK
If you’re creative, roll your survival bag up and strap it under the cross-bar to give you some padding
Don’t forget your whistle and waterproof
I don’t recommend sunglasses. They’ll either steam up, or get covered in mud, or both
Wear an MTB helmet and use the visor to stop mud splashing in your eyes
Do your helmet strap up tighter than normal as it’ll get shaken all over the place
Don’t strap the timing ‘dibber’ too tight near your wrist, otherwise it’ll dig into you
Carry necessary tools, pump and tubes – don’t expect any other riders to stop for you if you have a problem
If you arrive on a road section on your own and can see a rider ahead of you going about the same speed, do what’s necessary to catch them, and then work together
Watch out for rocks and stone water-channels on the downhills, particularly Whernside. It’s still possible to pinch-flat with 80psi in your tyres – you’ll be crying for your full-sus !
And don’t worry about the riders who get bike changes – they only do it to get faster bikes (with smooth tyres) for the road sections, and then change back again before heading offroad – tossers
The organisers and marshalls are brilliant – thanks them as you pass by, if you’ve got any breath left 😉
Have fun – it’s probably the only time you’ll descend like a maniac on rough rocky trails on a CX bike, and the scenery is stunning
