)Run of the week was thru West Ham Park, then along the Greenway to Stratford High Street then thru Olympic Park back on Greenway to Old Ford Locks then to Temple Mills and back home again via West Ham Greenway. This took two hours (and resulted in an 'oribble blister in my left foot)
Inside the Olympic Park you actually pass Second World War London machine gun pill box and anti-tank defences, which are almost next to the
Olympic stadium (see picture).
There was a number of defensive rings built around London against an expected German invasion.
I once went on a West Ham Labour Party historical tour of the area led by a local historian who explained about the defences and that the final defensive ring in London was around Whitehall. The Prime Minister, Winston Churchill was reputed to have vowed never to leave in the event of an successful invasion and to have pledged to remain and defend London to the death. You could imagine his final counter attack against the advancing enemy while smoking his trademark cigar, with a glass of single malt whiskey in one hand and a Tommy gun in the other.
