Former champion jockey Lance O'Sullivan and racing administrators Simon Cooper, Andre Klein and Jason Fleming are on course to run around the racetracks at Dargaville and Ruakaka this week.
The quartet began their run of the country's 51 licensed galloping tracks on Easter Monday, at the Gore racecourse as part of a six- day fundraising tour for The CatWalk Spinal Cord Injury Trust.
The public are invited to join the group for each run and donations can be made at all tracks. The runners are expected at the Dargaville track on Friday about 6.20pm.
A spokesman for the Dargaville Racing Club said it will also collect donations for the trust at its autumn meeting on April 20.
The run at Ruakaka will take place on Saturday at 7.30am. Joining the four racing representatives will be three former Northland rugby players, David Holwell, Justin Collins and Hayden Taylor.
