On 20 June 2016, Tesch was robbed of her bicycle at gunpoint while on a fitness ride with her physiotherapist in Rio de Janeiro, in preparation for that year's Paralympics. She was uninjured but shaken after the attack. Tesch and Fitzgibbon won back to back Paralympic gold medals by winning the SKUD18 at the 2016 Rio Paralympics. They won eight out of 11 races and came second in the other three.
