It's a bit more complicated than that...

Ah. I should have said that we cycled 100% of the legally cycleable bits. We ignored the routing up the hill round the town centre and pushed through the one-way street instead!
There was another tandem who overtook us just before the monster climb on the military road, and sped off the hill rather more quickly than us. Another one arrived at the chain ferry just after us. On the chain ferry we also bumped into someone who'd started at the Wootton camp-site (so had quite a way to go), and who said she'd found it very hard going, even though she was used to loaded touring.
Kudos, incidentally, to the young lad (15-year-old?) on the Apollo mountain bike - knobbly tyres and all - who made it round just after us. That was certainly a bike I'm glad I wasn't riding!
