Doing relay Triathlon 10km cycle.. advice?

[oldroadman]

If you don't want to buy

clip-on tri bars, you can try leaning your elbows on the handlebars with your hands in front. I reckon it gives a (slight ?) aero advantage* - but it is a bit wobbly, so try before you do it 'for real'

.

* it makes you think you are going faster anyway

... provided you don't wobble too much

Don't do it - it's daft and most amateurs/some pros can't do it safely. The slightest bump/irregularity in the road surface sees you in dnager of ending up on the tarmac. The advantage is negligible at the standard you mention - more power in the legs and lungs/heart is far more crucial.
Whare's the race? Round Gibraltar? Is the tunnel open again?

I only discovered very recently that there are actually two kinds of relay triathlon. One is the kind the OP is doing, where one person swims, hands over to another person to do the cycling, and the cyclist hands over to a third person who does the run.

The other kind (which I've only recently heard of) involves 4 people; the first person off does a (relatively short) swim, then bike, then run, then hands over to the second person who swims, cycles, runs, and hands over to the third person... you get the idea.

And there is another type of 4 man relay... http://www.clevelandtriathlon.co.uk/

So there are many types of pointless race? Ordinary tri (for people who are decent at one discipline and average at two) I can see why, relay where each person "specialises" in a discipline I can see why, but all the other stuff? Odd! Still, if it makes people happy and helps them get/keep fit, why not?

Absolutely. There's no way you want to take pointless risks at the speeds you should be going for this kind of race.
