Since June, runners over 50 have set six new road world records and world bests. A 50-year-old Kenyan broke a marathon record that had stood since 1991. A 70-year-old Canadian ran a marathon in under three and a half hours. A 90-year-old Scottish army veteran ran 10K in just over an hour.

Together they add up to one of the most remarkable stretches for masters road running in years. Here is who set each record, how fast they ran, and why it matters for every runner over 50.

Mark Kiptoo, 50: two records that stood for 35 years

For 35 years, South Africa’s Titus Mamabolo held both the M50 marathon and half marathon records, set at the same race in Durban in 1991. Mark Kiptoo took both in just over three weeks this October.

On October 3 he won the San Sebastián Half Marathon outright in 1:03:57, more than two minutes faster than the previous best for a man over 50. On October 25 he ran 2:15:24 at the Frankfurt Marathon in the rain, finishing 13th overall. That beat Mamabolo’s 2:19:29 by more than four minutes. The marathon time still needs ratification by World Masters Athletics.

Kiptoo has a long history of rewriting the masters record books. He made his marathon debut at 37, set a then over-40 world record of 2:07:50 in Frankfurt at 42, and ran 2:09:10 in Seoul at 47 for the over-45 record. His Frankfurt time this year was only about 7% slower than his winning time on the same course 12 years earlier.

Jennifer MacDonell, 70: a 3:23:59 marathon in Toronto

At the Toronto Waterfront Marathon on October 18, Ottawa’s Jennifer MacDonell ran 3:23:59, a new world best for women aged 70 to 74, pending ratification. That works out to roughly 4:50 per kilometre, or about 7:47 per mile, for the full 42.2 km.

Just nine days earlier, she set a Canadian age-group mile record of 6:51 in Montreal. MacDonell did not grow up as a competitive athlete. She told CTV News she wants to savor the moment: “You don’t get a world record every day, really.”

Ian Winship, 90: a 10K world best in just over an hour

On September 13, 90-year-old Ian Winship ran the Cumbernauld 10K in Scotland in 1:05:23 on the clock (1:04:37 by his chip). No man his age is known to have run a road 10K faster. His daughter and grandson ran the race alongside him, and he waved away the wheelchair paramedics offered at the finish.

Winship is a former paratrooper who served at Suez in 1956. He told PA Media the town might now be famous because of him. He has already said he plans to beat his own mark next year.

Clare Elms, 62: faster on the road than the track record

Britain’s Clare Elms broke the W60 5K world best twice this year. In April she ran 17:48. Then on June 2, at the Veterans AC Championships in Battersea, she lowered it to 17:45 and won the women’s race outright.

That time is faster than the women’s 60+ track world record for 5,000 m (17:50.72). On the 2025 age-grading tables, her chip time of 17:42 scores 105.73%, beyond what the tables treat as a world-class performance at peak age. In July she added a W60 3000 m track world record of 10:28.76.

Christine Kennedy, 71: a 1:35:40 half marathon

Ireland’s Christine Kennedy ran 1:35:40 at the Antrim Coast Half Marathon in Larne, Northern Ireland, on August 23. That makes her the fastest woman over 70 on the road-running masters record lists, improving on the previous W70 best of 1:36:13. Kennedy has competed at the front of masters distance running for many years.
