Ultra Marathons in London, in context
Verus covers 4 ultra marathons in London, out of 39 races there — roughly 10% of what is on here.
The dates cluster into 3 months — May, September and October — so there is a window rather than a rolling calendar.
Of those that publish an elevation figure, the flattest is Thames Path Challenge at 1,148ft of climb and the hilliest London 2 Brighton Challenge at 4,921ft — the same distance, but not the same afternoon.
If none of these fit, the counties where Verus covers the most racing overall are Hertfordshire (30), Kent (26) and North Yorkshire (23).
