I had the daft idea a few weeks ago of an up and down fell relay (where the first leg is mainly uphill, the second mainly downhill). That way great climbers could team up with great descenders. Also I thought, if such an event did exist, elite runners should be encouraged to run it solo, then only-moderately-elite teams have a chance of catching them.
I would like to point out that this is only hypothetical, and I have no desire to organise such an event. Not least because I can't think of a decent place to hold it without severe logistical problems.
So I figured if I put it to the forum, it would (a) give us something to talk about, and (b) someone might come up with a suitable location/route. Any ideas?
