Hey, dumbass. yes, you, Worthless Wiecky: Patrick *did* put it here,
hidden away in a larger post. I merely extracted something of very
great interest to many member of these conferences and gave it
greater, sole prominence. And to rub your nose in it, I republish the
public service health article in full below. As Patrick then goes on

Probably the most important public service announcement on these
conferences this year, I would say. Don't be so modest, Patrick.

You're going to think I'm the worst kind of moron, but when I first
got a heart rate monitor, I was brassed off that my heartrate would
fall so fast when I stopped exercising. I thought, What's the point of
all this exertion if not to get my respiration rate up? And then it
falls like a stone the minute I stop pedalling... "Ha," my physician
said when he next came cycling with me, "I know something the great
Andre Jute doesn't. Your heart rate is supposed to fall when you stop.
What sort of trainers did you have when you were a jock in your
youth?" Actually, those days the trainers would run us up a 45 degree
slope and down again until the last man lay face down in his
breakfast; nobody bothered about wimpy details like heartrate. We won
the President's Cup each of the three years I captained the team. Of
course, now running up that hill even once would probably kill me.

When I pass too many people, as sometimes happens, I start worrying
that I'm not taking in the scenery, and slow down. I start worrying
when the guys practising for the Connemara Marathon run past me. But
no, seriously, since I got a bike with automatic gears, I put my heart
rate on 80 per cent of max at the town border (just far enough from
home to warm up) and try to keep it there until I stop again, letting
the autobox take care of gradient and cadence. In short, I regulate
the entire ride by heart rate rather than speed across the road or any
of the other traditional methods (cadence never worked for me anyway
on the traditional style of bike).
