International representative rowing

coxless pair finishing well outside of medal contention. At the second of those WRC's in Lucerne he and Coudraye had success in a
Coxed pair with Toby Lister on the rudder. They won their event.[5] A month later at the
World Rowing U23 Championships in Brest, Belarus he rowed in the Australian U23 men's coxless four with
Will Lockwood,
Nicholas Purnell and
Joshua Dunkley-Smith and won the bronze medal.[6]
Later in 2010, in the southern summer and with another South Australian partner in
Chris Morgan, Grimm took a
coxed pair to the
2010 World Rowing Championships in Lake Karapiro, New Zealand. This time with
David Webster steering from the bow, the pair won the gold and Grimm's sole World Championship title. 2010 was his first and last international rowing representative season.[5]
