Stephen McMahon's 18 min 58 sec also run in 1989 created history with one school (and CHISSA/BAS) boasting four (4) Sub-19 minute Lap of the Lake Performers in the same year.
Breaking the 20 Minute Barrier is considered an outstanding performance at Open School level.
All 4 athletes (from St Patrick's College) claimed individual (Open) U.19 & U.20 Medals ( 1 Gold - S. McMahon, 1 Silver - C. Howley, 2 bronze - S. Carlson & R. Gleisner) at the 1989 Australian All Schools and Australian All-High Cross Country Championships in Adelaide and Sydney.
Due to the 1989 CHISSA Lap of the Lake being conducted only 2 days before the Australian Schools Cross Country Championships, the above athletes ran for places not times.
These 3 athletes also combined with Stephen Millichamp (Ballarat High School and Victorian All-High/VSSSA U16 800/1500M Record Holder) as a Ballarat YCW Club Team that claimed both the Victorian and Australian Under 18 4 x 800 M (7 mins 48.7 sec) and 4 x 1500 M (16 mins 4.1 secs) Relay Records on 17 & 19 December 1989 at Olympic Park.
