THE estate agent from Utah indulged in a triathlon training programme that at times was straight out of a couch potato’s handbook.

All the beer, pizza (cheese mostly) and heavy cream he could consume.

Rob Lea needed that not-so-routine diet to gain a little extra weight for his not-so-ordinary sort of climb, swim and bike endeavour he called “The Ultimate World Triathlon.”

Lea scaled Mount Everest through whipping wind, swam in the frigid waters of the English Channel while enduring constant jellyfish stings and rode his bike, through painful saddle sores, from one American coast to the other.

All in six months, too. He started on April 25 as he acclimated at Everest base camp and finished on October 7 by holding his bike aloft while standing in the waves.

He did take a brief timeout in the middle — to get married.

“What a great adventure,” Lea said in a phone interview.

The concept struck him while sitting in a doctor’s office. Dealing with ankle pain, the physician recommended he give up running.

His mind wandered. A former swimmer at the University of California at Davis, he began to think about the English Channel.

Then, a random thought: Would the English Channel or Everest be more difficult?

More thoughts: How about accomplishing both? Maybe a bike ride thrown in as well?

A plan was hatched.

Joining him on the expedition was professional ski mountaineer Caroline Gleich, who married Lea after the English Channel portion of the journey.

To train for Everest, the couple scaled Cho Oyu, which is one of the highest summits in the world. It’s also the spot where they took their relationship to an even higher plateau with Gleich proposing to him.

Lea said yes.

About two months before their Everest departure, though, Gleich tore the ACL in her left knee. She climbed Everest anyway.

Instead of trying to summit along the south side through Nepal (there was a viral photo of a traffic jam created by climbers waiting to ascend), they took a northern route. Despite all the wind gusts, they reached the summit on May 24 with the thermometer reading -35°C.

“I’m literally speechless and trying to find the words on what it all means,” Lea wrote on Instagram. “Guess it’s time to start thinking about swimming the English Channel.”

After arriving back in Utah, Gleich had surgery to fix her knee while Lea started his training regimen for the swim.

That meant gaining 30 pounds for insulation in the cold water. He ordered pizza from a local place in Park City that sponsored him. He drank Fat Tire amber ale courtesy of New Belgium Brewing. And he used plenty of heavy cream in his coffee.

It was gluttonous.

“I was eating slices of pizza in bed,” said Lea, who didn’t swim much because he couldn’t afford to burn off the calories. “I was eating even when I was full.”

The 38-year-old flew to England and started his English Channel trek on July 9 from Samphire Hoe at approximately 4:33 pm. No wetsuit could be worn (rules) so he donned a Speedo.

What helped early on were the jellyfish bites.

Sure, they stung, but they also provided an adrenaline rush. At one point, he went through a bloom of jellyfish. Now that didn’t feel so good. He got stung about 50 times.

Gleich offered constant support from the boat (no contact is allowed). Every 30 minutes or so she provided food and water. She also documented every swim stroke of the journey.

At about 4:22 am, he climbed onto the shore in Wissant, France.

It took less than 12 hours. He envisioned much longer.

“Reaching out and touching the sand on the French shoreline was a moment of joy, relief, confusion and elation,” he wrote on Instagram.

Back to Utah. More training awaited.

First, though, their wedding — on August 10 at the top of Snowbird Resort.

One slight hiccup: There was a massive rain storm leading up to their site and the road was closed due to a mud slide.

About 30 minutes before the wedding, the path reopened.

“Just like in our adventures, there were obstacles thrown at us and we had to make contingency plans,” he wrote on Instagram. “There were moments of distress and worry, but Caroline stayed calm and dealt with the adversity extremely well.”

No time for a honeymoon, though. A bike ride awaited. He began on August 30 from Anacortes, Washington, and got a flat tyre right away.

Gleich followed along in a support vehicle (Lea’s mom took over when Gleich had to go back to work). They stayed in motels at night, where they planned out the next day’s ride.

“The bike ride crushed me,” Lea said. “Every time I had a good day, the next day was super hard.”

On October 7 — day No 39 — he reached his destination of Nantucket, Massachusetts. Standing in the water, he held his pink specialised bike over his head to celebrate. Later, he cracked open a beer.

“I’m sort of speechless,” he wrote on Instagram. “I’m overjoyed and kind of emotional.”

Celebrating just as much that day was Gleich.

Through this endeavour, they wanted to raise awareness for gender equality. It’s bothered Lea that he’d be out skiing with Gleich and everyone assumed he was the guide and not her.

“Rob doing his alternate world triathlon isn’t going to directly change the world,” Gleich said. “Riding your bike, swimming and climbing mountains, they have just a really amazing power to bring people together. It’s a great starting point to talk about bigger issues.”

Lea’s already mulling over another adventure. Perhaps ski the largest mountain in Antarctica with Gleich?

It’s a thought for later.

“I just need a little bit more time for reflection,” Lea said.
