Time for a new design? (or just don't race on that track) Not every track suits the Beano so Steve only races on the ones that do. My Wasp used to have massive traction problems due to my light weight and being front wheel drive. I got a new bike in the end, with rear wheel drive.

All the best.

Dave, were you proposing to ride your high trike? I didn't realise it only had one driven wheel. I guess it would need a diff if it had two. I guess that is why everyone designs trikes with two front wheels and one driven rear. The only answer other than a different trike or bike would be to go slow enough not to lift the driven wheel in sharp corners. It's what I would do if it were me racing that kind of trike. Or use your Brompton.
All the best.
Roy

The Fast Saturday race on the Oval reminds me of the film "Death Race 2000"

Put a fixed wheel transmission on it and ride backwards...

(Interestingly, doing this was the only time I've ever found riding an upright trike to be completely intuitive.)

Can you not put the timing gear in the grass center of the oval, in the middle  of the lowest bend, then as that section is used by upper and lower tracks.....?

Oh, I will just ride the upright trike and moan about how much better I would have done if we were riding the other direction. That will conceal my lack of fitness quite nicely and preserve my fragile male ego when I get trounced by a little kid or something.

Most nice upright trikes have a double freewheel with half axles, so the power goes to the rear wheel turning the slowest. The exact same drive mechanism got purloined for the Quattrovelo. A differential pushes power to the wheel turning the fastest, so you lose drive every time you lift a wheel. Cheap trikes like mine use a one wheel drive that partially compensates for camber but is a pain when pedalling through a corner the wrong way.

No, because:

a) The lower bend of the oval is full of shrubbery (and occasionally junior cyclocrossers)
b) The cut-through that forms the lower loop of the track is separate from the oval
c) The green area on the space between them isn't tent-friendly (and appears to have a MTB underpass in it)

Personally, I think we should stick to using the oval and the full circuit, and having the finish line in the usual place on the north straight of the oval where there's a decent amount of space, good sightlines and low risk of crashes.  It would make timing operations considerably less stressful.  (It also eliminates a nasty hairpin and would be less of a trek to the facilities.)

Looks like the company that hosts the BHPC websites has been having connectivity issues.  It's reachable now (as evidenced by this post) but I'd suggest anyone intending to do a last-minute registration for Gravesend do it sooner rather than later, in case it goes down again.
