When I was a young lad, I didn’t seem to have a fear of heights, not that I got many chances to test it but a couple of things springs to mind. As a ‘feral youth’ I once climbed to the top of a factory building without fear. I won’t divulge any further detail, just setting the scene….. In the military, I was in the rock climbing club. Prior to that I was moved from ‘boxing’ as it was considered too dangerous for me (military logic!). Following that, I did take part in annual adventure training, participating a few times in abseiling, where I seemed to be happy to lean back into space and then propel myself down a rockface with some gusto. In my early 20s, that changed, I lost my confidence and no longer felt comfortable with heights and so avoided it going forward.
Fast forward to 2025 as we prepared for our recent holiday to Australia/New Zealand. Chris suggested we climb Sydney Harbour Bridge, emphasising the once in a lifetime chance. I was painted into a corner 🙂 At the time, I remembered a visit to the O2 in London and noticed they had a facility to walk over that dome and I felt confident that I could do it. At the time we parked the idea. Mention of the Sydney Harbour Bridge climb brought back that idea and we went on a London trip and booked in to walk the dome. Not as high has Sydney Harbour Bridge but it would be a good opportunity to provide confidence for the holiday. We both completed the O2 dome climb and it was a physical challenge but no real issues with the height – the views were really nice and so was the fish and chips on the banks of River Thames after! Click the picture below to read about that wonderful day.

January 2026. We arrived in Sydney late January and our bridge climb was all booked. In the end, I had no real issues. In terms of height, I didn’t have any issues. It was high and the views were tremendous – Sydney is known for it’s iconic look and the bridge is part of that. It was not as physical as the O2 but on a totally different surface.
I am pleased to provide some pictures from that event below. In the end Chris was right (as usual) – it would have been a shame to miss this challenge.
Yours

I have a personal interest in this subject because I had pulmonary emboli (PE) diagnosed in January 2011 around 6 weeks after I had major surgery.

Words are very important to cancer patients, some people hang their hats on them and put their feet up, and some people google them until they are tied in a knot, still fraught with worry.
