OXFORD University’s Boat Race squads endured mixed results on the London Tideway.

Nearly 500 fours and quads raced over the reverse of the Boat Race course in the Academic Championship events.

The top Oxford women’s four of Beth Bridgman, Tina Christmann, Lizzie Polgreen and Renee Koolschijn, with Michael Hobley coxing, suffered a mid-race entanglement with another boat and had to settle for second place behind the Light Blues.

The men’s four of Charles Pearson, Tobias Schroder, Augustin Wambersie, Felix Drinkall and cox Anna Carbery took the coxed four title, beating Cambridge by a second to reverse the outcome of last month’s British Championships.

At Challenge level, the Oxford lightweight women won with their coxed four of Caitlin O’Brien, Grace Joel, Brigitte Schmittlein, Fiona Jamieson and cox Charlotte Lee – their B crew coming home in second place.

Other runner-up positions went to the Oxford women’s and men’s coxless fours, as well as the women’s quad scull.

Oxford Brookes had very few boats entered, the most intriguing being a lightweight quad of Jamie Copus and Ben Reeves with two visiting Belgian internationals that finished third behind two GB international crews.

Wallingford RC claimed victory in coxless fours with Wallingford RC (Emily Wilks, Kat Butler, Bev Ashton and Hannah Slater) in the Challenge event with City of Oxford in third place.

Abingdon School saw their Junior Challenge crew of Matthew Bell, Joe McConnell, Ed Sharp, Charles Hall and cox Noah Walker win in a coxed four.

Abingdon also took third place with their Challenge quad, while Radley College were happy with third in the Championship coxed fours.

Hinksey Sculling School’s top finish was second place for the women’s junior Challenge quad scull.

The following day saw around 250 Masters rowers take to the water, with success for Falcon and Wallingford boats.

Falcon’s crew of Alison Salvesen, Camilla Scarf, Alison Grünewald and Julie Summers won in the D age group and Wallingford’s John Wiggins, Judith Carr, Andy Knight and Becky Waller were dominant in the Mixed E category.

Wallingford RC’s Charles Parry reunited with the composite crew that won at the Henley Masters in July to win the G age group by more than a minute.
