The 40-year-old, now competing in the masters category, is eyeing Bernard Lagat’s 2015 mark of 27:48, with his personal best currently at 27:38, which was set in 2013.
His recent form includes a third-place finish at the Cape Town leg of the series in May, when he clocked 28:06.
“Over the past two years, I’ve been running faster, but this time I need to dig even deeper,” Mokoka told SABC Sport.
“Bernard Lagat had to travel from the U.S. to race in Manchester. Here at home, Absa is giving us the opportunity to compete locally in various cities against some of the world’s best young talent.
"These young guys are running well – you can’t reach the podium anymore with a 28:10. I’m excited with the way my training is going, and the platform this incredible event provides. I’m hopeful I can break the master's record.”
Lagat also broke the world masters record in 2015, which was witnessed by Mokoka himself, and nearly a decade later, he now finds himself chasing that very mark.
"I can say it’s a goal. I was there the day Lagat set the world master’s record. Time really flies. Hopefully, with good weather this time, I can achieve it," he added.
Coached by Michael Seme, he continues to train alongside younger athletes at the University of Johannesburg and recently joined the Zoo Lake training group, led by Hendrick Ramaala.
“It’s not easy, but the young guys at UJ are pushing me hard—they really burn my chest—and the past few weeks have been enjoyable.
“It’s great to learn from others. The Zoo Lake route is tough, but I enjoyed the challenge. Joining different groups keeps things fun and helps me improve,” Mokoka concluded.
