Flyjeffva . . .sorry to hear about your wrist, gaurds are a good idea. I am now considering the flexmeter wrist guards, but have concerns about the restriction of movement making braking more difficult. Are you looking at the ones that have a splint on both sides or just on one?
Roger Davies he also mentioned wrist guards, and your right to say that its not a bad idea for new riders. I’m going to go try on a few different makes this weekend.
On the subject of Roger, just gota say I was lucky enough to have him answer the phone at http://www.unicycle.uk.com/ when I first inquired about getting a 36". I told him what I planned to do (London to Brighton) and his advice has been invaluable. He’s has been a great source of information - and has made time to talk me through some of the finer points distance riding. His support has been fantastic.
Thank You Roger 
My 36" Nimbus ‘Impulse’ Unicycle with ‘Shadow’ Handle arrived today and I’m half way through setting it up, had to stop because off school pick-up time! Cant wait to jump on it and ride off, or more likley, fall off. 
Johnfoss . . . Thanks for your advice, not surprisingly you and Roger have similar ideas on how to do it.
The glucosamine supplements are something I hadn’t considered, and at my age I probably should. Do you only use them on the day of the ride, or is it an all year round kinda deal? Regarding braking, Its on my to do list. Crotch and knees are also where I feel it, but I’m sure that riding the 36" longer distances may also get my legs and lungs too!
The London to Brighton is defiantly gonna be a blast, so long as i get my training in.
Question . . . Should I be learning the 36" with or without shadow handle attached. I’m tempted to try it with, as that’s the set-up that I’m planning on using.
P.S. This being my first thread, I’m amazed and delighted by the response from the unicycling community. Just goes to show what a great bunch we all are.
