That film also features a rider who'd forgotten their leg-warmers on an East Anglian 300 in April, that had temperatures from -2 to 18C.
I remember that ride -and said rider complaining at having cold legs. It was one of Herman Ramsey's if I recall. The water in my bidon was part frozen by the time we got to the first control, at about 1am, only to find it locked up because the local who held the keys to the hall had mixed up a.m. and p.m, and poor Herman was reduced to serving orange juice from the back of his car.
The Windflower 300. I'd just got a Fuji M603, which was essentially the first vlogging camera, recording VGA at 30fps. SVCDs were the most practical way of showing the results, which meant editing at 29.97 fps. That set a scene length before the sound and vision went out of synch. That kept the editing snappy, terrible sound though.
I've still got the SVCD of that ride somewhere. It was a 1am start, and we got to the first control at 6am, having gone off course. We were freezing and looking forward to a bit of a warm. Being East Anglia there were no shops or cafes until a cafe control South of Cambridge, over 100km in.
We met Yoshi Sekido at the start, and learned of the expatriate Japanese community around Croydon. He was perplexed by the instruction 'S.O at Village Green', which kept popping up. He wondered if it was some sort of light.
Heather was determined to finish PBP2003, having packed in 1999. We did loads of extra riding, especially when it was hot. She got a bit of heat exhaustion on a ride to Kendal and back at about 33C. We were near Carnforth, so we went into Booths supermarket and rested bags of frozen peas on her forearms. The PBP route seems to lack those sort of facilities, but they are just off route.
Another key tip is to avoid riding into controls at full speed. The cooling effect of the moving air is suddenly absent, and when you stop you'll be immediately bathed in sweat, your blood will be diverted to your skin, and you'll fall over. Cooling down for the last Ks is a good idea.
