I rode it on my DynaTech last year - great day, great weather and great crowd. The pie and peas tasted like heaven on earth by the time I'd finished!
A 'long' 50+ miles if that makes any sense with climbs that, although not uber steep, eat away at your energy as the day goes on. There's a great section just over halfway way as you descend gently along the river for ages and you feel like you must be near home... sadly, there's a couple of sneaky beggars in the lasy couple of miles that finished me off (I particularly remember a nasty hairpin bend coming back into town where my wobble nearly had be tumbling at less than walking pace).
Highly recommended event and, subject to injury or mental fatigue from attempting the Tour of Flanders (read: beer/frites overdose) the weekend before, I expect to be there again.
