Runner Eilish McColgan has been told to wear a medical boot – after discovering the injury she sustained during the London Marathon is worse than she thought.

The Scots athlete revealed her health setback in a post on social media as she posed for a photo wearing a controlled ankle movement (CAM) boot – also known as a 'Moon Boot'.

Her update comes after she sustained a toe injury midway through the London Marathon in April, forcing her to battle to the finish with blood seeping through her running shoes.

The 35-year-old star posed for the new photo during a weekend in London, smiling broadly in front of the Holy Trinity Church in Westminster, despite the unfortunate development.

In a message posted alongside the image, Ms McColgan, who is the daughter of Scottish running legend Liz, wrote: ‘New fashion accessory!

‘Thought I had got away with London Marathon toe gate, but sadly not... thankfully it's nothing too serious and I'll be back doing what I love in a few weeks!

‘It's been an expensive weekend in London but using girl math I've balanced out the sad expenses with some happier ones - retail therapy, a West End show, posh hotel and lots of good food.’

The running star also lamented that the last time she had been forced to wear one of the orthopaedic boots was in 2015, which she described as a ‘horrible year’.

Discussing that period, she wrote: ‘I broke my ankle and spent something like eight months in a boot before having surgery.

‘Thankfully this is a breeze compared to then. Only a few weeks to endure!’

McColgan completed the London Marathon in seventh place finishing in a time of 2:24:51.

She revealed details of her toe injury shortly afterwards, saying it 'felt like her foot exploded' and that she could hardly feel any pressure running through it towards the end.

She later recuperated from the injury by taking time out to enjoy a beach holiday.

McColgan suggested a swollen foot may have led to the injury, with the British star explaining she had suffered from a rash in the build-up to the marathon which had spread down her calves.
