meh not to heavy really then! would you class 5 miles as a long run? furthers ive gone in the hill with the trailer and that weight is 15!! you do need a support bike though...Snacker says itl carry 350kg. No idea what it weighs. Manager told me he is wanting away from Honda because they are too soft.
The estate is all ground types from Grade 3 Arable, rolling lowland right upto bracken hill and peat moor with a windfarm at top. From the main steading up to the back of the hill will be 5 miles if not more.
