Just did 15 miles on the bike to Windsor and back. Outward via roads return mainly along the River Thames towpath. Places of interest passed Windsor Castle, Irish Guards statue in Windsor, Windsor Racecourse (Bob The Builders on stage today) Eton College (Olympic) Rowing Lake, People Bungee jumping from a crane, Heston Blumenthal & Giancarlo Caldesi's restaurants in Bray (was close to Roux Bros Waterside).
