Darren Edwards, who is paralysed from the chest down, has been taking part in the World Marathon Challenge to complete seven marathons across seven continents in seven days - all in a wheelchair.
After completing the sixth marathon in Fortaleza, Brazil, he headed off for the final leg in Miami.
Having completed the Brazil leg in two hours and 36 minutes he said: "We started the penultimate race of our World Marathon Challenge this morning in growing heat and humidity, making it tough work for everyone running.
"Despite the challenge of logistics - amongst other hurdles - we have persevered with grit and determination. I finished today’s marathon in two hours and 36 mins, which I am happy with! So, one final marathon, this time in North America and at Miami, Florida. Here we go!"
He has now raised more than £45,000 for the Armed Forces Para-Snowsport Team because they helped him change his life since becoming disabled.
