• Thomas urged on Instagram and X that any coach implicated in doping be barred for life from working in the sport.
• She added that athletes who choose to train under coaches with known doping histories are complicit.
• The sprinter pressed for clearer processes and more respectful conduct from testing officials, citing her own interactions with anti-doping staff.
• As context, Thomas has long disputed a 2020 AIU whereabouts case, saying phone data and witnesses placed her at the listed locations and alleging protocol failures.
• The AIU said Ruth Chepngetich tested positive for hydromethiazide and issued a provisional suspension, prompting Emma Bates to question whether athletes lost rightful wins and to highlight agent Federico Rosa’s history with doping-linked athletes.
