A CARING brother has completed three Ironman challenges in three days to raise money for charity after his sister was diagnosed with breast cancer earlier this year.

Steve Purchell, 31, decided to take part in the challenge to raise money for Macmillan Cancer Support after his sister Hannah Woodward, 34 from Tilehurst, was diagnosed with breast cancer in April.

The challenge, which took place last weekend (September 11, 12 and 13) saw Steve swim a total of 7.2 miles, cycle 336 miles and run 78.66 miles across three days.

Steve completed the swimming sections at Tri2O Swim Centre in Burghfield before completing the cycle ride and run.

So that people could join if they wanted to, Steve ran past Little Heath Park every day.

Across the three days, various people joined in with different legs of his challenge including runners who ran a marathon with him having never done one before.

Steve explained there were points when he was "really struggling" but he kept on going for his sister.

During his challenge on Sunday he said he was in a 'pain cave' for hours where he said he could only focus on the pain he was in.

He explained he had a nap on the side of the road and carried on.

As encouragement to push through the difficult stages of the challenge he had stickers on his handlebars with motivational quotes.

He explained: "When you’re at your lowest you have still got to keep going on chemotherapy no matter what.

"I could have stopped but she (Hannah) was my motivation to keep going."

Steve's initial fundraising target was £1,200 but the total now stands at £4,660 which Steve described as "incredible".

He said is is "over the moon" and "blown away" by people's support adding it "shows how amazing people are".

Hannah said she thinks her brother is "amazing" for what he has done.

She explained so many people watched him during his challenge and there was a "massive buzz".

Hannah revealed she found a lump in her breast in April and was diagnosed with breast cancer.

She started chemotherapy in May and has had it every three weeks.

Steve said he is proud of his sister who he described as "so strong".

When Hannah shaved her hair following chemotherapy, her three brothers did the same in support.
