Where it hurts
The Limehouse Tunnel
Easy to go too fast downhill, then a climb out at mile 2.
The Wapping cobbles
Short, but watch your footing.
The last bridge
A final climb with 500 metres left. Use the drop after it.
Elevation
About 93 m of climbing over 13.1 miles, in short pieces: out of the Limehouse Tunnel, into Canary Wharf, up to Tower Bridge and over the last bridge before Greenwich.
