I checked... Kew Bridge to Henley, via a circuitous route to follow the Thames (Richmond > Kingston > Hampton > Datchett > Windsor > Henley) is about 55 miles.
It could be done as a leave-early thing... but we could also take a more direct route and only follow the River Thame as a way to avoid Heathrow and Feltham... once past there straighten up and ride direct.
Regatta!
