Indian Pacific Wheel Race - IndyPac - IPWR

Those articles aren't written with ultra racers in mind. The power output for most of us is lower, after a couple of days, so losing 6 W when you're only putting out 80W is more damaging.

Hadn't thought of that.

But even on those numbers, 6 min per 100km is 5.5 hours, or 100+km, so still worth having.

That did occur to me, but I forgot to mention it.

(It's an autumn ride so quite a lot of dark, + gadgets, means people with dynamos would use them most of the time).

I hadn't thought of that either: Oz = sunshine to me. But that could swing both ways, as more use means more frequent charging.

Ultimately though, an ounce of experience is better than a pound of internet wisdom, so I'm not going to argue with you: I'm just trying to bump my post count...
