3Down is a pretty good one from what I remember. Though angry New Forest drivers are the worst.
You could probably ECE Kennet Valley Run quite easily https://audax.uk/event-details?eventId=7359 -if you could find a nice route to the start and back home then it'd probably add up to 300km.
Kennet Valley looks good actually - not touched a lot of the stuff below Newbury. Just getting West out of London that's a pain, though I'd potentially just get an early train to Guildford or something to avoid it.
