Nearly one and half thousand people are due to take part in a triathalon event at the Holkham estate in North Norfolk this weekend.
The Outlaw Half Holkham triathlon will see the super fit, take on a 1.2mile swim, 56mile bike ride and 13.1mile run in an expected heat wave this Sunday.
The race starts from 6.22am with a lake swim next to Holkham Hall, the bike course will test the legs on local roads and all of the half marathon run course is within the grounds.
Local clubs will be out in force competing and volunteering. Tri-Anglia, TRISudbury and Beccles Tri Club will be among those involved.
While the athletes at the front of the field will be racing for prize money, many will be raising money for charity, including the official charity, Cancer Research UK. Spectators are welcome.
