Big vote for Snowdon. 3rd time this year.
Greensands
Beachy Head
Loch Ness
No experience of any others, mainly 'cause I enjoy Snowdon so much.
Jersey is great, but I may be biased....
I'm off to Budapest this year, but did Liverpool last year and that was brilliant, especially the experience of coming out the tunnel!
Oh, and Jersey has a steady climb, but not too steep from 2 miles to around 5 miles then is pretty flat, with a bit of downhill around mile 20... Some of the race is also off road, but the trail is pretty firm....
UK - New Forest or beachy Head are definitely worth looking at.
Berlin is an epic city, amazing place to visit. Especially if you like a drink or two! Marathon-course is PB-tastic.
