Seven World Records! Meet the athletes who rewrote the record books using CurraNZ

CurraNZ® is increasingly becoming the go-to supplement for athletes attempting extreme world records, when their mind, body and spirit are on the line.

Superb muscle recovery and large-effect endurance-promoting functions make CurraNZ a proven weapon for athletes when the going gets tough in these feats of human endurance.

Here’s our ‘who’s who’ honour roll of people who have etched their name in history using CurraNZ.


1. Kiko Matthews – Guinness World Record: Fastest Woman to cross the Atlantic solo, 2018

British fundraiser Kiko Matthews smashed the Atlantic solo rowing record by an unthinkable six days when completing the crossing in 49 days, 7 hours and 15 minutes. She became only the seventh woman to achieve the feat on her first-ever attempt at the 3,000-mile crossing.

Kiko, who had never rowed before the challenge, described CurraNZ as ‘my blackcurrant lifesavers’, for days involving up to 15 hours of rowing.

“I literally cannot believe I rowed 3,000 miles and barely had any muscle pain at all. It’s unheard of and I cannot attribute this to anything else other than the two doses of CurraNZ I had every day.”

Kiko raised over £100,000 for Kings College Hospital in London, after they provided her with life-saving treatment and neurosurgery for Cushings Disease.


2. Neil Hunter – Guinness World Record, First Diabetic adventurer to cross Antarctica unsupported, December 2019

The Brit from Surrey completed a 730-mile skiing mission in 51 days and became the first insulin-reliant Diabetic and one of fewer than 30 people to reach the South Pole unassisted.

The 48-year-old dragged a 100kg-loaded carbon fibre sled whilst skiing for up to 11 hours a day, for almost two months.

A long-time user of CurraNZ, Neil relied on our supplement knowing it would enable him to recover quickly from his daily exertions and support his endurance.

“This wasn’t about earning accolades but raising awareness about Diabetes and proving that your body will do so much more than you think it can.

“It was logical to pack CurraNZ for my once-in-a-lifetime adventure because I know that it really works for me.”


  1. Andy Stone – Guinness World Record: 70 Half Ironman Triathlons in 72 days, June 2022

In 2022 British man Andy Stone set a new Guinness World record with 70 consecutive Half Ironman triathlons in just over 70 days on Friday, June 17.

The relative newcomer to triathlon was recommended CurraNZ by Liverpool John Moore’s University researcher and nutritionist, Dr Juliette Strauss, when fatigue and recovery became a problem when only halfway through his 5,000-mile challenge.

With its endurance, fat oxidation and muscle recovery benefits, Dr Strauss recommended CurraNZ for Andy’s daily 70.3-mile exertions. 

By day 33, Andy had endured a week of feeling tired and was losing confidence that he could complete the challenge.

He started CurraNZ on day 33 and immediately saw the benefits, reporting: “Incredibly, on the first day of using CurraNZ, I set new cycle and swim PBs and probably would have gone on to have a run PB too if I hadn’t been joined by a supporter that day!"

Needless to say, Andy didn't look back and set an impressive new record. 



 5. Guinness World Record – The Longest Continual Workout, June 2022

In the summer of 2022 a CurraNZ-powered team of 12 from a London gym set a new record for the longest continual workout of 40 hours.

Mimi Gardner, one of the 12 who earned the world record, said: “The team loved using CurraNZ, which helped us battle through.

"I felt physically very, very well after the 40 hours of nonstop moving and exercising - most of it was quite hardcore. In fact, I felt better after that than I did after running a half marathon when I wasn't taking CurraNZ!"



5. Joasia Zakrzewski – 48-hour World Record 411.458km (255.668 miles), February 2023

Jo Zakrzewski set a 48-hour world record of 411.458 kilometers (255.668 miles) on her first attempt at the two-day format in the Taipei Ultramarathon earlier in 2023.

The Scottish GP, now living in Australia, surpassed the previous record of 403.32km (250.611 miles) set by Patrycja Bereznowska of Poland on May 15, 2022. For good measure, Jo also surpassed the men’s Scottish and British records too.


6. Sam Harvey – Guinness World Record assist (683km) and World Record tie, 101 laps (667km) Backyard Ultra, June 2023

Kiwi Sam Harvey equalled the world record for most laps in a single Backyard Ultramarathon by running 677.31km – or 101 laps – at an event in Australia.

In doing so, he was the crucial ‘assist’ for Australian record-holder Phil Gore to complete 102 laps after Sam was forced to withdraw due to pneumonia.

A race that spanned five days of continuous running, the Australian record was broken on lap 76 and then the American record was passed on lap 85. Harvey Lewis, the American record holder, made up the trio leading into the last night but dropped out on loop 90. 

Sam and Phil tied the world record distance of 101 laps, equalling the previous ultra-distance benchmark set by two Belgium runners in October 2022.

After setting off for loop 102, Sam was turned back by medics, tapping out after 101 hours. Phil managed one more lap to set a new world record of 102 loops or 683km.

7. Andrew Heyden - Guinness World Record, fastest marathon run by a Monk, May 2019

Long-time marathoner and ultra-runner Andrew Heyden achieved his World Record when running the fastest marathon as a monk in 2:43 in the Sydney showpiece. 

Andrew had intended to set the record to become the fastest blackcurrant to run a marathon, but unfortunately the title wasn't available from Guinness. 

We'll need to speak to them about that!
