We caught an Uber to Waterloo Station at 10 am to link up with Brakeaway Bike Tours. There were nine of us on this bike tour, two Aussies, two Canadian girls, two Chinese girls (who actually managed to get lost in the first 100 metres!) and us. Our guide Charlie had a great (dry) sense of humour and was fun to be with for the four hours we were on the tour. The bikes were basic but had seven gears and very comfortable seats. We learned a lot about London history that we didn't know previously. Charlie took us to popular spots as well as little side streets and alley ways that connected us from backwaters to mainstream attractions. As we had already seen many of the main attractions we found the backwater places he took us to be of more interest but the background info Charlie gave us at each place we went was interesting and informative anyway. Did you know for example that 'toeing the line' comes from the red line drawn on each side of the debating chamber in the House Of Commons which is exactly a sword length and one pace on each side as all MPs are apparently entitled to carry a sword into the house and 'toeing the line' ensures they can never damage each other! The route taken did cross some busy streets but at no time did we feel unsafe. Charlie was always conscious of keeping everyone together. Clearly you see so much more in the same time on a bike than walking (we even got a 30 minute lunch break) and much more flexible than being on a bus. After the bike tour we decided that we might do a river cruise down to Greenwich and take in the Borough Market on the way. We bought hop-on-hop-off tickets on the clipper express from London Eye (which was a five minute walk from where we dropped the bikes off) and hopped off at Bankside to take in the market. It was a typical foodies-paradise-type market and to be frank if we lived here there were a lot of temptations! We then caught the ferry (which are almost the same as the Brisbane River catamarans) to Greenwich. Greenwich had their own market too which had much more variety and was nice to wander through. Greenwich has a nice 'vibe' and it is clear a lot of Londoners like to go there on the weekend to enjoy it. Food tents and entertainment on two different sections and plenty of open spaces and greens that families were enjoying plus plenty of eateries. We had tea and scones here, tea was great, scones another story... There is actually a foot tunnel under the Thames there built between 1898 and 1902 that we stumbled across so we walked under the Thames and back again just to tick that box. We then caught the ferry back to Tower Bridge (close to an hours wait as people were heading back to Central London). We started to pack for our flight out next day, watched the Black Ferns win the Women's World Cup on TV and then went out for dinner close to 10pm. Slim pickings, so we ended up at a cheapish Indian place but the food was ok. Tomorrow afternoon we leave for Shanghai.
