Flat point-to-point from Blackheath to The Mall. Passes iconic landmarks — Greenwich, Tower Bridge, Canary Wharf, Embankment, Buckingham Palace. Very fast course.
April in London: 45–65°F with possible rain. Overcast and cool is typical. Rarely hot but 2018 hit 24°C and caused widespread DNFs.
Water every mile; Lucozade Sport (isotonic) at miles 5, 10, 15, 19, 22. Own nutrition must be carried as no gel stations.
No gel stations on course. Athletes who don't carry their own fuel are entirely dependent on the sugary Lucozade Sport sachets — fine for some, a GI disaster for others.
