Defending men's champion Richard Ussher will seek a fifth title when the 30th edition of the coast to coast multi sport endurance race is held next month.
Last year Ussher won the individual longest day event by 15 minutes to set the second fastest time for a race win.
Ussher's wife Elina, the 2010 winner and runner-up last year, will race again and the pair could become the first husband and wife to win the event in the same year.
