Regarding Jud's comments about good climbs in other states...
One of the good things about riding Brevets on the national, or even international stage is that you get to discover plenty of truly good climbs. For some reason, Brevet organizers usually tend to give you rather more climbing than typical Centuries organizers. Don't know why, but this is a fact.
The worst (or best, depending on how you look at it) climb I am aware of on US Brevets can be found on Davis Bike Club's superb Gold Rush Randonnee (a 1200k Brevet that takes place every 4 years - next edition, hopefully, in 2009; see my report of the 2005 edition on this site under Rides Reports). You hit Janesville grade upon leaving Susanville on the way back, and you suddenly realize why the organizer advised you to come with small gears. The climb is long (gutfeeling is about 3 miles at least altogether), never drops below the 12% mark, and hits probably very close to 20% two thirds up the way. It's pretty scary the other way too, you can reach ridiculous speed on the lower, straight section. I can claim with no risk of being challenged that this is by en large the toughest climb to be found on a 1200k Brevet, worldwide. Any of the legendary BMB hills is little training stuff in comparison.
Closer to us, Boston-Montreal-Boston is a real feast to the hill-lover. If you are looking for a tremendously rewarding day out, just ride the stage from Brattleboro to Ludlow and back. It's a bit under 200k and has no less than five large hills plus countless smaller ones. The toughest one being Mount Terrible inbound, just after leaving Ludlow. The beauty of this section is that you won't find gradient much worse than 10%, but you will find a lot of climbing. Altogether I would estimate the length of climbing to be perhaps 40 miles out of about 115 miles total.
If some of you want to ride this section, drop me an e-mail and I will arrange a cue sheet, given a decent advance warning (i.e. no less than two weeks).
If you feel like travelling for discovering great climbing, our friends of Audax UK run an 'Audax Altitude Award' scheme that highlights the hillier events on their Brevet calendar by giving them so-called AAA points. The scheme has gained over the years a very loyal fan-club (of which yours truly used to be part of when I was living over there), and more than a few AUKs set-up a target number of AAA points as part of their objectives for the season. Let me suggest a sample of some of the best events offering AAA points, many of which I have personally ridden, and survived, if somewhat sore for a little while afterwards:
Cotswold Corker Populaire, 1890m/108k, Cheltenham, February 10th. A winter classic!
Gospel Pass Brevet, 2280m/150k, Chepstow, February 24th. Another classic, with snow on the pass more than occasional. One of those rides that go somewhere.
Taith Mynydd a Mor, 3449m/200k, Llanelli, March 18th. Great tour of South Wales. I think translation means something like 'tour of mountain and sea'.
Dorset Coast, 2900m/207k, Wareham, April 1st. The best 200 in Southern England in my humble opinion. And yes, you will ride over roman roads. Just try to find one in America!
3D300, 4400M/315K, Dorchester, April 15th. The toughest 300k I have ridden to date (out of a dozen), and one of the most rewarding.
The Elenith, 4727m/305k, Kidderminster, April 21st. Another classic across the desert of mid-Wales!
Brian Chapman Memorial, 8450m/616k, Chepstow, May 19th. All of Wales in a week-end. Many swear this is the best 600 on Earth. Bad weather guaranteed, by the way.
Dales Grimpeur, 4596m/215k, Pateley Bridge, June 2nd. The toughest 200 I am aware of. Makes Tom's PA200 seem flat.
Down with the British, 3805m/201k, Cardiff, July 14th. An immensely rewarding and scenic tour of the mining towns and valleys.
Worcestershire and South Cotswold, 4240m/300k, Droitwich, July 21st. 'Few have finished', in the very words of the organizer! I have, so many of you can, too.
Kidderminster Killer, 3937m/202k, Astley, September 9th. The annual struggle (e.g. walk for many) up Asterton Bank in the Welsh Borders.
Dartmoor Devil, 2320m/106k, Bovey Tracey, October 28th. The ultimate end-of-season classic all over gorgeous Dartmoor.
And, not least, the Maniac 1000k is available as an AUK Permanent. 17000 metres of climbing for 1000k, going all over the Pennines. Cue sheet is an A4 simply listing the towns where you need proof of passage, with free route in-between - but the towns are cunningly placed so that you can't avoid the big climbs. I am aware of just two people having completed this absolute monster since its creation many years ago. There is a (deserved) signpost '30%' on Hardnott Pass, actually. Your chance to enter a very select club!
