I think London is slightly downhill. Same Edinburgh. I'm sure these are fine... but there must be some sort of limit for, say, world records to be allowed to go into the books.
Some half marathons and 10Ks have elevation drops too.
So, is there an officially accepted maximum elevation drop that's allowed for road-race world records - and is this the same limit that should be used for Personal Bests?
Any ideas, or links, would be welcome.
