A cancer survivor is official the world’s first woman that managed to complete the “Sea to Summit” triathlon.

The woman swam, cycled, and ran over 330 miles in the span of 5 days.

Andrea Mason did not sleep and barely ate anything during the duration of the insane triathlon.

But after she crossed the finish line at a very early point, she was ecstatic.

The race that she took part in was carried out in the French Alps.

She swam around the Lake Annecy, cycled up, and ran at the Mont Blanc, which is 15,774 ft and is the second-highest peak in Europe.

Mason, who is 39 years old, battled through extreme pain, cramping, and hallucinations, however, she pushed on and managed to complete the race.

It only took her 4 days, 23 hours, and 41 minutes.

In 2017, Andrea was diagnosed with a rare type of cancer along with endometriosis and cervical cancer, and needed life-saving surgery.

After a successful operation, she is now hoping to raise awareness of women’s reproductive health.

Last year, Andrea set up the Lady Talk Matters, a charity, in order to normalize conversations that surround female reproductive matters.

Andrea, who is from Blackpool in Lancashire, England said that she felt happy, exhausted, and relieved after completing the race.

She added:

I am so happy all went to plan as there were so many things that could have gone wrong. I wanted to do it in five days, and I did, but it was tough, really tough. I had some low moments, particularly when I couldn’t sleep in my limited rest periods, and when I couldn’t keep any food down as I was running. For sure I had some doubts along the way. I was venturing into the unknown with such a huge run, particularly as large parts of it were in the dark. It was bigger than I imagined, the impact on my body was huge, but every time I felt like stopping and considered giving up, I kept remembering why I was doing it. I thought about all the women out there in pain or who still hadn’t been diagnosed. That is why I put myself through this.

If you are wondering what she had to do in order to complete the race, here it is.

Andrea had to swim 23 miles around the circumference of Lake Annecy, cycle 205 miles with 30,000 feet of vertical climbing around Mont Blanc, and run 105 miles with 4,000 feet of vertical climbing around the Ultra-Trail du Mont-Blanc.

All cheers to Andrea and good luck to her!
