The 1.9km swim leg is set in the fresh, calm waters of Lake Burley Griffin, commencing from Canberra’s Commonwealth Park opposite the race finish arch.

It is a one-lap rectangular design of 1.9kms in length, in water approximately two to four metres in depth and approximately 19/20 degrees Celsius. The entrance and exit for the swim leg will be via the entry point and a pathway marked to T1. The swim leg will feature a deep-water start and competitors will complete one lap.

Should the temperature fall well below the norm, due to unnatural or freak conditions, it is possible the swim could be shortened. Wet suits and an additional cap/s are advisable in such conditions.

Paddlers and IRB rescue boats will be on the course at all times to provide a safety cover. The swim course closes 1:00 hour after each official wave start time.

WATER TEMPERATURE & QUALITY

Water quality in Lake Burley Griffin is constantly measured through the auspices of the National Capital Authority. The Technical Delegate for the Ironman 70.3 Canberra will take a temperature reading 24-hours prior to race start and this will be posted at Race HQ as the “Interim Temperature”.

Based on this reading a wetsuit ruling will be made and posted on the noticeboard at race headquarters.

A second reading will be taken 2-hours before race start and a final wetsuit ruling made and announced to competitors at the Sunday morning competitor briefing. Competitors should bring their wetsuit on race day.

NOTE: You can check the current water quality in Lake Burley Griffin, by checking the Urban Services website and going to the Lake Burley Griffin tab, and then to the Weekly Lake Update/Report  tab.

Note 2: Ignore all reports outside of the Central Basin, as that is the only part of the lake used by the Ironman 70.3 Canberra.

We’ll post a direct link to the latest info on the lake courtesy of NCA well before the event…
