It has been described as the ultimate challenge.

And one Lowestoft man has begun his quest to complete seven extreme events, back to back, over seven days this week – in memory of his brother who died six years ago.

Personal trainer Curtis High has already conquered a major fear in completing the first challenge of his ultimate iron man fundraiser.

Yesterday (Monday), Mr High, 30, completed a tandem skydive at Ellough Airfield and today he has been joined by boxer Anthony Ogogo at Bannatyne Health Club in Lowestoft to row the equivalent length of the channel.

The pair both rowed 37,000m – which equates to 23.125 miles – on two water rowers at the health club where Mr High works.

Ahead of the second gruelling challenge, Mr High said: 'This is almost a marathon in itself and it does feel in a way like you are rowing on the water. But after completing the tandem skydive challenge, the worst out of all of them has been done already. Flying is a big fear of mine, and I was very nervous, but it was awesome.'

Between April 17 and Sunday, April 23, Mr High will be raising money for the Taylor High Memorial Fund. His parents Elaine and Gary High set up the fund in his brother Taylor's memory, after the popular teenager died in a crash in west Norfolk in 2011. Since then the fund has raised more than £93,000 for deserving causes and made more than 80 donations across Waveney.

Tomorrow Mr High will swim the 3,700m width of Loch Ness in the Bannatyne's swimming pool, cycle 50 miles on an exercise bike, climb the height of the Eiffel Tower on a climbing wall at Waterlane Sports Centre, compete in the East Anglian Triathlon and then finish the week by running the London Marathon.

Motivated by raising awareness and money for his brother's fund, Mr High said that after each day's challenge he would be taking 'lots of ice baths' and was aiming to get lots of rest in preparation for the events ahead.

He added: 'I'm really proud to have Anthony here. It's really amazing of him to give a whole day of his time and I really appreciate it.'

Gary High said: 'We're really pleased that Anthony has got involved – it's fantastic to have an Olympic bronze medallist helping the fund.'

Mr Ogogo said: 'When Curtis asked me to get involved I was over the moon. I've known him a long while and we used to do lots of training together, I am only too pleased to help. The Taylor High Memorial Fund is such a great charity, which helps local people in need, and I can't commend them enough.

'Hopefully I can help Curtis with my presence here, helping to pace him along – that is what friendship is all about.'
