Earlier this year in Barcelona, Jacob Kiplimo delivered one of the most jaw-dropping performances in distance running history. The 24-year-old Ugandan covered 13.1 miles in a stunning 56:42 — a half marathon time 48 seconds faster than the previous world record.

Now, just two months later, Kiplimo is in London for his much-anticipated marathon debut. The buzz is growing louder: could he break the marathon world record? Could he even challenge the two-hour barrier in an official race? London Marathon event director Hugh Brasher believes we could be about to witness something historic.

“I think it’s going to be the most fascinating debut ever,” Brasher said. “Is it feasible he could take Kelvin Kiptum’s record as the fastest debutant? Without a doubt. Could he eventually become the first man to run under two hours? Yes. But let’s see what happens on Sunday.”

Kiplimo’s story is remarkable. Growing up on a farm 1,500 meters above sea level on the slopes of Mount Elgon, he found inspiration in his older half-brothers — Robert Chemonges and Victor Kiplangat — both of whom would go on to become world-class marathoners.

“We were helping our brothers, the big brothers,” Kiplimo said. “We would see them training and I told them: ‘I want to become like you.’ So I just kept training.”

By 15, Kiplimo had been spotted and brought to Italy to prepare for the Rio Olympics. Although he exited in the 5,000m semifinals, the experience launched his international career. His early times were already astonishing: 13:19 for 5,000m and 27:26 for 10,000m — all before the supershoe era.

While his track career was hampered by the lack of a blazing sprint finish, Kiplimo found his true strength on the roads. He went on to win two senior world cross country titles, along with Olympic and World Championship bronze medals in the 10,000m.

Sunday’s London Marathon will be his toughest test yet. He will face one of the strongest fields ever assembled: Eliud Kipchoge, Olympic champion Tamirat Tola, defending champion Alexander Mutiso, and Sebastian Sawe — who ran 2:02:05 to win Valencia, the second-fastest marathon debut in history. British eyes will also be on Olympic triathlon champion Alex Yee, aiming for a 2:09 debut.

Kiplimo says he is ready. He has built up his weekly mileage from 75–90 miles during his track days to 125–135 miles for the marathon.

The lead pack is expected to hit halfway in around 61 minutes, setting up a possible negative split. With a favorable tailwind forecast in the second half — though temperatures could be on the warm side — conditions could be ideal for something special.

Kiplimo has already shown he can rewrite history. On Sunday, the world will be watching to see if he can do it again.
