The new agreement – which extends to the end of 2024 and includes the Olympic Games in Paris – comes as the Dundonian distance runner aims to continue her incredible run of form at the upcoming World Championships and Commonwealth Games.

Lindsays, which has offices in Edinburgh, Glasgow and Dundee, has provided support to the 31-year-old athlete since 2013.

Ms McColgan, who this week announced her intention to compete in this year’s London Marathon, said: “For me, it’s important to have people like those at Lindsays who have stuck with me through my athletics career. This year has been incredible for me and I’m super-excited by what lies ahead this summer, but I’ve also had some difficult years along the way.

“It’s amazing to have the support of a firm like Lindsays who are there for you during the good times and bad, whether I’m winning medals or recovering from injury or illness. It motivates me to continue doing what I’m doing because I have that support behind me. I feel as though I have the right people in my team - including Lindsays - and I am grateful for their support over the years.

“Lindsays has made an investment in me, not just as an athlete, but as a person. They appreciate it’s not all going to be smooth sailing and their sponsorship for me is, in many ways, unique and family-like. I feel as though I have a really close relationship with Lindsays.

“I’m incredibly lucky to have strong relationships with all of the brands I work with, to have them in my corner - and for all the wider support I get.”

Ms McColgan set a new British and European 10k record in May’s Great Manchester Run, having already broken Paula Radcliffe’s British half-marathon record in February.

Lindsays chief operating officer Ian Beattie, who is also chairman of UK Athletics, said: “We are delighted that the firm has been part of Eilish’s journey for so long and to be able to offer her our continued support. She is in amazing form and does so much to inspire people with her determination and achievements. I’m sure there are a lot more exciting times ahead.

“On and off the track, Eilish is a remarkable role model for young Scots and a great ambassador for Scottish sport. It’s a source of huge pride for us to be able to call her a friend of our firm.”
