Route Description
This route is simple enough that it doesn’t need much of an explanation.
You’ll begin at the London start pens with a flat, 1.5km lead-in that takes you across the Tower Bridge and into The Underground.
The road will tilt upward soon afterward, then you’ll cross the KOM start line for Fox Hill. From there, you’ve got 2.4km to the finish line at the end of the timed Fox Hill segment.
The Fox Hill KOM segment is 2.4km long, but the final 1/3 is flat or downhill. Good luck!



I guess they ran out of route names then 🤷♂️
That’s the climb championship? With all the iconic climbs that they have available, they chose a 2.4k 4.3% grade? Why not have them ride the “Epic Run” with the finish at the Radio Tower?
Was the original Fox Hill shorter?
from the train depot to the start of kom was extended to fit a right and left roadways.
No, far as I recall it’s never changed.
