It's not so much the guys at the front that I'd like to adjust, it's the ones at the back. Every year the top guys end up catching the guys at the back. This, as we all know, gets bl**dy dangerous. How about...........

The first 20 (or so) start at 10 sec intervals, and the rest start either, 5 secs apart, or in pairs, 10 secs apart.
That would reduce the whole race start by approx 45%, and remove the situation of riders being lapped (breakdowns, bad running bikes and remounts excepted).

Merry Xmas, Pete
