IT is the Mother of All Challenges... but Leigh McLean is confident she can succeed.

The mum-of-three is joining The One Show's Alex Jones and three other mums from around the UK to take part in Sport Relief 2018.

The Mother of All Challenges for Sport Relief, will see the team push themselves to the limit as they face a series of five gruelling challenges across six days - including swimming in Loch Ness, cycling through the Lake District and coastal running in Wales.

It will raise awareness of maternal health issues, something close to the group’s hearts as each of the four mums has experienced their own maternal health issues.

Leigh lives in Bearsden with her husband Colin, and her three children.

When Leigh met her husband, she already had son Ross from a previous relationship, and they hoped to try for another child.

After struggling to get pregnant, Leigh and Colin decided to use IVF treatment.

Leigh discovered it was a subject that wasn’t often discussed and had trouble finding someone who she could talk to about IVF.

Following this, Leigh openly talks about her experiences of, going through two cycles of IVF.

The first time Leigh miscarried but the second time was a success to full-term, and Leigh gave birth to twins, a girl and a boy.

Leigh said: “I think I’ve gone through every emotion possible. I started at the ‘totally bricking it’ stage and have now settled down to ‘quietly apprehensive but excited’.

"Being part of a team of mums and knowing that we will raising money for Sport Relief to support incredible causes makes a massive difference.

"I’m not sure I would be able to do this on my own, having the girls and Alex with me means we can support each other.”
