Jamie Laing is gearing up for an intense Ultra Marathon challenge to raise funds for Red Nose Day this March. 

And the former Made In Chelsea star and broadcaster, 36, is already raring to go, having kicked off his training this week. 

He was seen sporting his best workout gear for his first training session ahead of the Radio 1 challenge.

Beaming with excitement on a red race track, Jamie wore a red Comic Relief vest paired with black workout shorts. 

He layered up with a black sweatshirt and completed the look with a pair of high-performance running trainers. 

This will be Jamie's greatest physical and psychological challenge yet, as he takes on the monumental feat starting March 17 during the Radio 1 Breakfast Show with Greg James.

The route will take him through cities, towns, and villages where Comic Relief-funded partners provide vital support to those in need. 

Radio 1's Ultra Marathon Man: Jamie Laing for Red Nose Day, will see him tackle daily ultra-marathons over a five-day stretch, pushing his limits to cross the finish line in Salford, live on his drive-time show Going Home with Vick, Katie and Jamie on March 21. 

Jamie follows in the footsteps of his Radio 1 co-stars who have taken on previous, epic Red Nose Day challenges.

In 2023 Mollie King tackled a daunting endurance cycling challenge for Comic Relief, raising more than £1.3million.

In 2022, DJ Jordan North completed a 100-mile relentless Red Nose Day row whilst in 2018, Greg James took on the Gregathlon: Pedal to the Peaks. 

The news comes after Jamie shared the terrifying moment he first discovered he suffers from tinnitus as he offered valuable advice for others facing the same condition.

In a recent appearance on This Morning, the reality TV star joined Dr Raj Arora to discuss his struggle with tinnitus, a condition affecting around 7.6 million people in the UK.

Speaking with hosts Cat Deeley, 48, and Ben Shephard, 50, Jamie recalled the moment, nine years ago, when he woke up to a ringing sound that wouldn't go away.

He explained that he thought the noise was coming from somewhere in his house, but then he realised it was actually in his ear.

Jamie has previously compared the noise to a constant high-pitched sound, akin to a dog whistle.

The primary symptom of tinnitus is hearing a ringing or buzzing sound without an external source.

Although the exact cause is unclear, tinnitus is often linked to hearing loss or other conditions such as depression and anxiety.

During the show, Jamie shared how the condition affects him daily, admitting: 'It is pretty debilitating.'

'My story is that nine years ago, I woke up one morning and could hear this ringing. So, I searched my whole house then I realised it was in my head.'

He continued: 'The hard thing about it is no one can see it or hear it, so it's a very solo problem.'

Jamie described the sound as a 'high ringing whooshing noise' that becomes louder the more anxious or tired he feels.

When asked about the possible cause of his tinnitus, Jamie speculated that it was likely due to years of not protecting his ears.

He admitted: 'I think my thing was I never protected my ears - I went to a lot of nightclubs when I was younger.'

The reality star also shared some helpful tips for those suffering from tinnitus, revealing that listening to white noise, whale sounds, or even the hum of a fan helps him sleep at night.
