Race two of the BikeFit Marlborough Winter duathlon series takes place on Sunday from the Wither Hills farm park walkway entrance off Forest Park Drive in Blenheim.
Jeremy McKenzie has dominated the Marlborough scene for the last couple of years and won the opening race of this series, but organising spokesman Steve Smith was not sure if he'll be racing on Sunday.
Jess Barnes is favoured to take out the women's race – the main event contested over a 5km run, 8km cycle, 1km run course along the bottom of the Wither Hills and up towards the Taylor Dam.
Registration starts at the start/finish line near the car park at 9.30am and racing starts at 10am.
