Duncan Goodhew’s 100 metres breaststroke gold was one of the most memorable moments of the 1980 Olympic Games in Moscow, and you’ll be pleased to know he has kept very busy since.

Instantly recognisable due to his complete baldness – the result of a medical condition – Goodhew was one of the iconic British athletes, captain of the swimming team and latterly an MBE for his services to sport.

At the Moscow Games – which several nations boycotted on account of the Soviet invasion of Afghanistan – Goodhew competed under the Olympic flag, as did many athletes wishing to participate while still staging a protest against the war.

Having won silvers and bronzes in breaststroke and medley events at the Commonwealth Games and World Championships, Goodhew was a known quantity and by 1980 was skipper of the British swimming team.

He went into the final as the fastest qualifier and favourite, and did not disappoint, holding off the Soviet Union’s Arsens Miskarovs by almost half a second.

Since then Goodhew has used his profile and enthusiasm to help promote swimming for all abilities: with Team GB and the Olympics, in schools through coaching, at grass-roots level with mass-participation events, and commercially with sponsors.

So what is he up to now?

"In addition to working with the BOA as a Team GB ambassador both for swimming and the table tennis players, I’m working on organising and promoting the Swimathon," Goodhew, 54, told Eurosport.

"Swimathon is a mass participation swimming event that we started in the 80s in response to the success of the London Marathon. Unfortunately we can’t get 30,000 people in a pool so we’ve taken advantage of what swimming has to offer – this year we have 650 pools taking part.

"We’ve made it very flexible towards different abilities – you can have a team of any ages, composed how you like. I watched a team of five octogenarians, and another time I was with Daniel – aged four – who swam two lengths while his parents swam 180.

"Over the years these swimmers have raised £34 million in charity; this year we’re raising money for Marie Curie’s Cancer Care. This year is different from other years in that we have a Big Splash Mile event in aid of Sport Relief, so you can just sign up for a mile swim.

"Hopefully we’ll get a lot of people involved – at the moment we have 5,000 people already registered, which puts is well on track to get over 20,000 people signed up.

"Aside from my Team GB and Swimathon work, I’m an ambassador for the British Gas swimming programme (British Gas sponsors the national championships and many swim teams), I do lots of motivational speaking, and do promotional work for Southern Water’s ‘learn to swim’ programme – this year we put half a million kids through the programme.

"In terms of business, I’m also a director of Premier Sport, which is the number-one sports coaching company into primary schools, coaching 200,000 children nationwide.

"Another company I’m a director of is Limelight Sports, which won sports agency of the year for 2011. We deal with grass-roots, mass participation events.

"We’re going to be working alongside transport for London to deliver the ‘people and traffic flow’ for central London, and all the events outside the stadia. We are very experienced with traffic and people management in London, so we are dealing with a lot of practical aspects of the barriers and the marshalling.

"To be involved in the Olympic Games in all these ways is terrific. I live in London now so it’s particularly exciting for me. I moved up from Somerset because of the amount of travelling I was doing, and am based in South Kensington, nice and close to the Serpentine where I was swimming until it got chilly in October.

"It’s going to be a fantastic time to be here and we’re all delighted to be involved."

Swimathon takes place on the weekend of April 27-29, raising money for Marie Curie Cancer Care. Sign up for individual 2.5k and 5k events or the team 5k event, or the Big Splash Mile in aid of Sport Relief, by clicking on the link below the photo.
