Really enjoyed the route. The crossings meant I ran some sections I haven’t before. Building work in central made it hard to navigate at times, as did the tourists! Oh and the steps, nice reprieve from the running early on, but not so much later in the run.
My distance came up a little short once I’d crossed Tower Bridge, so I kept going until I’d reached 50k.
carried 3 bottles of lucozade and a bag of sweets from the start, on what turned out to be a warm day it was just enough.
