The Tour de Yorkshire's toughest ever stage will take place later.
With eight categorised climbs along the 194.5km route, the Bradford to Fox Valley stage three has been dubbed 'The Yorkshire Terrier'.
It features eight classified climbs, including four in the final 22km loop.
Caleb Ewan currently leads the race overall after two days of cycling, which have seen Dylan Groenewegen claim the first stage from Bridlington to Scarborough on Friday and Nacer Bouhanni win stage two from Tadcaster to Harrogate yesterday.
The women's race, which was a one-day event contested on the same 122.5km course as the men's second stage, was won by Otley's Lizzie Deignan.
Today's finale to the three-day men's pro event will follow one of the largest amateur sportive cycling events on the British calendar, with thousands of riders saddling up for a gruelling ride around Fox Valley.
