Cheating allegations have disrupted the Totalsports Two Oceans Half Marathon powered by BYD after two male runners reportedly competed in the women’s category using female race numbers, both finishing inside the Top 10.

The breach was uncovered through a disciplinary sub-committee chair and running blogger who flagged the incidents, identifying cases where one male participant ran using another athlete’s bib to place seventh in the women’s race, while another entered the same category using a transferred number and finished tenth.

The actions violated race rules and triggered scrutiny over event controls, with organizers and officials now reviewing how ineligible entries bypassed verification.

The fallout directly affected legitimate competitors who were pushed down the rankings, including athletes initially placed just outside the Top 10, with one amateur runner losing a rare top-tier finish.

Both ineligible results have since been removed and disciplinary proceedings initiated, with sanctions expected to include multi-year bans for both participants and those who enabled the entries.

The individuals involved issued apologies, citing errors in judgment and last-minute injuries that led to transfer of entries, while investigations continue into wider race-day irregularities affecting hundreds of runners across different categories.

Additional checks revealed broader rule violations beyond the women’s category incident. More than 140 ultra marathon runners and over 250 half marathon participants reportedly started ahead of assigned batches, resulting in time penalties and pending reviews that could escalate to disqualifications.

A further group of runners faces possible sanctions for using race numbers across different events on separate days, adding pressure on organizers to tighten enforcement systems and restore competitive integrity across one of the region’s largest road races.
