I rode it on a rigid in 2010. Easy is not a word that springs to mind, the same applies to a HT, one other rode a HT that year, again, young, skilled and found it harder than a FS (His words) I think an adaption of Crocodile Dundee’s words cover it…”You can ride it on a rigid/HT, but why would you if you’ve got 150mm of travel, its much more fun!”
Fair play to Dreamer, inspirational to me at that age, I’m mid 40’s and it was definitely physically hard but entirely achievable with a bit of preparation.
I think the 6 consecutive days is less of the issue than just getting the right level of fitness in the first place to enjoy it. You can always get through it, but to enjoy it at the time being fit is better!
You would want to up the amount of riding you do over the once a week, but that could be done by turbo sessions if need be. I’d concentrate on upping your threshold fitness, so try riding the 35miles at the weekends increasingly fast. That way you are able to operate at lower levels for longer. You don’t need to just keep riding further and further, that just takes longer..
Sorry if that’s long..the summary is, its the ride of a lifetime, do it,it changed everything I wanted to do on a mountain bike :-)….and I bought a Full Suss as soon as I got home 😉
