SCS alumna sets Guinness World Record with six Ironmans
Southern Cross Schools alumna Daniella Cowden has set a Guinness World Record by completing six Ironmans across six continents in 147 days.
HOEDSPRUIT – Southern Cross Schools (SCS) alumna Daniella Cowden, a member of the Class of 2016, has achieved a remarkable endurance feat after completing six full-distance Ironman triathlons across six continents in just 147 days.
The achievement earned Cowden a new Guinness World Record, capping an extraordinary six-month journey that began with Ironman South Africa in Gqeberha in April and concluded in Hokkaido, Japan, in September.
A journey across six continents
Her challenge took her through Brazil, Australia, Spain and Canada before the final race in Japan.
Across the six events, Cowden completed approximately:
- 22.8km of swimming
- 1 080km of cycling
- More than 253km of running
She covered around 1 356km of racing in total.
Reflecting on the journey, Cowden described the night before the final race as an emotional one on Facebook, filled with nerves, excitement, gratitude and relief.
“Six Ironmans. Six continents. Six months. Done,” she said in a post.
The toughest race
The final event in Japan proved particularly demanding. Cowden experienced significant back pain during the 180km cycling leg, with the discomfort setting in much earlier than she was accustomed to.
Rather than allowing the pain to derail her race, she focused on small milestones along the route, including downhill sections, sheltered stretches and the prospect of seeing her family.
The marathon that followed was equally challenging. Maintaining what would normally be her easy running pace felt difficult, but Cowden eventually found a steady rhythm and continued kilometre by kilometre.
The final 45 minutes, run in darkness, were among the toughest moments of the race. After 12 hours, 36 minutes and 31 seconds, Cowden crossed the finish line in fourth place in her age group.
A proud moment for SCS
Cowden grew up at Simbambili in the Sabi Sand and later qualified as a veterinary nurse. She is currently based in Dubai.
For SCS, the achievement is a source of immense pride. The school celebrated its former learner’s world-record accomplishment and the determination, discipline and mental strength behind it.
Cowden also paid tribute to her parents, friends and family for supporting her throughout the demanding journey on social media.
