The winner of the Centennial Cup for 2021 is Sierra Ryland – one of only 2 people to dip under the handicapper’s prediction on a blustery South Coast day. Not far behind Sierra was Brett Hawthorne, also under his predicted time. Harry McLean, James Coventry, Anthea Oliver and Karen McLean all battled it out for 3rd place.
The fastest women on the day were Amanda Broughton (19.50), Heather Walker (20.2=04) and Emily Solsberg (20.45). The fastest men were Ben Twyman (16.34), James Richardson (16.47) and Jack Shaw (16.56)
