I went to support a fellow runner in the Richmond running Festival 2016 10k. It starts in Kew Gardens (Free Entry to spectators!!) and finishes in Old Deer Park near Richmond Town Centre…it’s where one of the parkruns are. the route winds through Kew Gardens (very scenic) and down the Thames Towpath (very scenic).
Similarly for the HM and Marathon except the Marathon goes further down the towpath to Kingston Bridge and back to the same finish. Very scenic past the Polo fields and Ham House and Teddington Lock. Also past the little-known open water swim venue at Thames Mariners in Ham (look for RGActive). You’ll likely engage with Olympic canoeists/kayakers, sailors on yachts and rowers en-route.
You get the point! UK’s most scenic City Marathon/HM by a looooong way I would have thought.
It’s a super-flat course. A little bumpy in places and a little over grass at the end.
My fellow runner didn’t quite manage to beat either Jo Pavey or Andrew Baddeley.
Might be worth a 2017 diary-entry?
