(OOC: Well, world record marathon winners seem to be able to do it in a little over two hours--that's not bad In fact, that's much faster than I had you guys going. With the Barbarian's Con, I'd expect better than the world record )
OOC: True but most of them are wrecked after they finish, and definitely couldn't repeat the performance four times in one day, not even considering they'd also have to keep it up over the following two days as well (that's ~12 marathons in 3 days), plus they're not carrying any kind of load.
(OOC: Well, given the barbarian's Strength, carrying a greataxe and a twenty food tub full of molten gold is probably to him like the marathon runner's shirt and bottle of water is to them )
OOC: Marathon runners don't usually carry a bottle of water, but then apparently the don't wear anything other than a shirt either. So, what's a coach or boat trip going to cost, as we're going to take forever on foot?
(OOC: Yeah, I thought you were somewhere else I think--they don't really do 300 mile coach trips. However, looking at the map again, the boat looks very attractive, although it is upriver.)
(OOC: That depends on how much style you want and what kind of ship. Stylish and fast ships are more expensive. Slow-moving refuse barges heaped in garbage where the PCs hide and wallow in the garbage to avoid paying are cheaper )
