Another glorious weekend awaits with the eighth annual Chiltern Wonderland 50 upon us. 250 runners will descend on Goring on Thames to see if they can complete this stunning trail 50 mile loop and it's circa 6000ft of climbing to make it back inside the 13 hour cut off.
Below is a quick look at the likely leading contenders. Live tracking will be available as always from 0830 on Saturday 16th September via the link here (will be updated to the CW50 table just before race day).

Sophie Biggs: Last years champion finished in 7:55 for her debut Centurion win, after a third place at the NDW50 earlier in the year. Sophie was sixth at the Hundred Hills 50km back in March and has since gone on to a win at Maverick X Ultra - Peak District and a third at the Serpent Trail 50km.
Amy Sole: Amy leads our 2023 Grand Slam 50 mile standings with an eighth, a fifth and a third at the previous three 50s so far this year. Second at the Arc 50 in 2022 as well, she is incredibly consistent over this distance on trail.
