Women's marathon world record holder Ruth Chepng'etich./FILE
Ruth Chepng’etich may have opted for a voluntary provisional suspension, but the world half-marathon record holder still retains the right to challenge the process before the Athletics Integrity Unit (AIU), and possibly the Court of Arbitration for Sport (CAS).
Chepng’etich was provisionally suspended on Thursday after testing positive for Hydrochlorothiazide (HCTZ), a diuretic listed under class S5 (Diuretics and Masking Agents) on the World Anti-Doping Agency (WADA) Prohibited List.
