Tom Cooper took out the South Canterbury Athletic Club's annual one-day decathlon bragging rights, but only by a small margin.
Cooper notched up 5200 points over the 10 events with Philip Butler just seven adrift, while Hamish Dewar was third.
Held at the Aorangi track, 17 athletes ran, jumped and threw their way through 10 gruelling events in very warm conditions.
Normally held during two days, the condensed event makes it more challenging and exciting.
There were many top performances throughout the day with athletes achieving personal bests in several events.
Noteworthy efforts included an impressive discus throw of 51.18m by Cooper and an excellent 400m time of 63 seconds by Anna Haywood.
Simon Small, Butler and Cooper all cleared 1.8m in the high jump while masters athlete Wayne Doyle impressed with a 400m time of 60 seconds.
Final Results: 10 boys: 1 Theo Jones; 12 boys: 1 William Valentine, 2 Thomas Valentine, 3 Nick Bradshaw; 12 girls: 1 Anna Hayward, 2 Nuala Jones; 13 boys: 1 Michael Russell, 2 Cameron Bruce, 3 Finn Nicol; 14 girls: Christina Ryan; 18 men: 1 Hamish Dewar; 20 men: 1 Tom Cooper, 2 Bradley Laing; senior men: 1 Philip Butler, 2 Simon Small; Masters: 1 Clayton Murray; Masters (40+) 1 Wayne Doyle.
