This week, Sam & Katie chat with up-and-coming triathlete Jack Caldwell. Hailing from Eden on the Far South Coast of NSW, Jack has been training from a young age. A naturally strong swimmer who also shone in school cross country, Jack eventually combined both strengths—adding cycling into the mix—to discover his talent in triathlon.
After playing a range of sports growing up, Jack began racing Sprint Triathlons throughout high school. Earlier this year, he claimed the Men’s Junior Title for the Oceania Region in Devonport—clocking a blistering 15:15 5K off the bike. He also boasts a 14:56 PB from a Sydney workout, and fondly recalls defending his Panboola Wetlands parkrun course record.
Jack was all set for World Tri in Wollongong, but a pair of stress fractures and other setbacks have forced some recovery time. He’s now building back gradually, with eyes on moving to the Gold Coast in 2026 to train full-time.
🏋️♀️ Training Weeks-
Katie hits 3 x 1K off 90s (3:20 splits) plus some 400s off a 200 float. She’s taking a weekend off with suspected iron deficiency, rounding out at 63 km for the week.
