Kevin Sinfield has completed his latest energy-sapping fundraising challenge to help people living with motor neurone disease.
The 43-year-old former rugby league star crossed the finishing line to a rapturous welcome on The Mall in London on Thursday after running seven ultra marathons in seven different cities in as many days, once again inspired by former Leeds Rhinos teammate Rob Burrow's MND diagnosis.
Sinfield and his team took to the roads once again to raise awareness of MND and funds for five charities supporting people affected by the condition and their families, and also to fund research into effective treatments and ultimately a cure.
Each leg has comprised 27 miles - the conventional marathon distance with an extra mile added to signify how much further people can go to help friends in need - with the aim being to complete it in under four hours.
Their target was to raise Stg 777,777 ($A1.5 million) to help around 5000 people currently living with MND in the UK.
As Sinfield untied his shoelaces, the total had passed the Stg 630,000 ($A1.2 million) mark with more than Stg 94,000 ($A179,600) pledged in Gift Aid.
The former Leeds Rhinos, England and Great Britain rugby league loose forward, currently defence coach for England's rugby union team, has spearheaded a campaign which has already raised more than Stg 8million ($A15 million).
He and his team set off from Twickenham at 12pm on Thursday having already completed 27-mile routes in Leeds, Cardiff, Birmingham, Edinburgh, Dublin and Brighton.
