ATHLETES competing in the latest round of the Hervey Bay Triathlon series will dip into unchartered waters on Sunday - a swimming pool.
Organisers have had to move the location of the aquathon race due to the blue blubber jellyfish that have inhabited the waters along Hervey Bay's beaches.
The event was scheduled to be held at Ron Beaton Park in Torquay, but the swim legs will be held at Hervey Bay Aquatic Centre.
The decision comes just a few days after the Australia Day Club 2 Pub ocean swim was postponed due to the plague of jellyfish.
Hervey Bay Triathlon Club president Ron Morgan said the club was simply taking precautionary measures and was relieved they had an alternative to make sure the race could go ahead.
"It's only the second time in probably 15 years that we have had to change or altered an event," he said.
The format of the opens race will comprise of three 2km runs along the side of Raward Rd, Torquay, and two 400m swims in the pool.
While it's the first time the swim portion of a HBTC race has been in a pool, Morgan was still expecting strong numbers to turn out.
"I think it is quite exciting and will be a fast race," he said.
"I expect to see a lot of action and because it is something different I think most people will enjoy it for a change.
"Because it is in a small area, it will also be spectator friendly."
For many the first race of the year will be a chance for athletes to burn off some of the Christmas turkey.
Morgan expects the youngsters to set the pace.
"These sorts of events (aquathons) favour the younger contestants," he said.
That is music to the ears of junior coach Brian Harrington.
Harrington, who is also the Wide Bay and Queensland state schools triathlon coach, said about 30 young athletes will use Sunday's race as a warm-up to next month's state titles at Redcliffe.
Junior races start at 5.45am before seniors get going at 6.45am.
Registrations will remain open until the start of races and late fees have been waived.
