Hi Jerrys
I’m one of the event organisers. I’d say it’s a fairly close call on this one, but on balance, I’d probably say the CdF. Senor J is right, there are some tough sections early on where you might wish you were on the MTB, but later when you get onto the faster and firmer drove roads, you’ll be glad to have the CX under you.
Those early field sections are forced on us by necessity unfortunately, as one section of our preferred route tends to get wrecked by 4x4s, creating some deep, flooded mud holes on what should be a good stretch of track. It’s just in one corner of the course though, and we rejigged the route last year to take out a hard MTB biased climb early on and get that field section out of the way quicker, and put in more distance on the northern return part of the route, which has generally better all weather surfaces. We think that has balanced the course out in favour of the cross bikes a fair bit, but this is a pretty tough course all round – the climbs out of the valley on both sides are pretty big and steep!
Hope that helps make your mind up. I’ll be around at the start and finish on the day, so say hello if you do come and ride!
