She then handed him the certificate and continued: 'And your second, the fastest time to complete a 104.6-mile triathlon on seven continents, which is 21 days, nine hours and 18 minutes.
'Congratulations, you are officially amazing!'
Alison told him: 'Spencer Matthews, you are an icon! Well done.'
Ben added: 'I am so glad you got home safely, we'll look forward to seeing the film when you eventually get it together and put it out.'
Speaking about why he wanted to do it, Spencer said: 'I enjoy pushing myself, and challenging myself mentally and physically.
'After the 30 marathons last year, I wanted to expand on it, add a few elements to it.
'I noticed a young man in Canada who had done seven Iron Men triathlons on all seven continents, one on each continent, I thought what an incredible challenge and how cool it would be to follow in his footsteps.'
The star explained that the previous man had done it in 3 years and 11 months, while he did it in 21 days.

He also touched upon the tough times throughout the feat.
Spencer said: 'Huge highs and lows, anyone who has done an Iron Man will tell you it's pretty hard to enjoy the full day.
'Highs and lows, the extreme lows, I had to remember why you're doing it, set a good example for my kids.'
One moment in particular did worry him, as he explained: 'The Cape Town swim was pretty bad, nine degree water.
'I was in there for 90 minutes, there were seals that were in and around me splashing over me, I'd been told that morning that there were problems with rabid seals in the area.
'I'm not sure if they were joking or not, but it didn't feel like a joke at the time.'
Spencer revealed that he had completed his epic challenge of seven Ironman triathlons on seven continents in just 21 days on Thursday.
He shared on Instagram: 'AFTER A 28 HOUR 51 MINUTE WAR WITH ANTARCTICA, I'M DELIGHTED TO ANNOUNCE THAT THE JOB IS DONE.... I DID IT, PROJECT SE7EN IS COMPLETE!!! WHAT A MAD MOMENT THIS IS!!'
'I'm now a 3 x Guinness World Records holding athlete. The two new records are: Fastest 140.6-mile triathlon on Antarctica (28 hours 51 minutes 11 seconds) Fastest time to complete a 140.6-mile triathlon on seven continents (21 days 9 hours 18 minutes)'

He looked thrilled to be home as he was surprised by his three children, Theo, seven, Gigi, five, and three-year-old Otto, at the airport.
