A man is in a critical condition after suffering a heart attack midway through a Hamilton cycle race.
Waikato police Senior Sergeant Mike Henwood said the man, 73, was cycling along Tauwhare Rd, on the outskirts of Hamilton, in the Winter Fun Ride Series about midday when he suffered the heart attack.
Cordons were eventually put in place and saw cyclists diverted up Bruntwood Rd, along Brinkworth Rd and down Lee Martin Rd.
He is currently in a critical condition, he said.
Henwood expected the diversions to be lifted soon.
