Aprot was less successful in the 2011 season, managing only fifth in the junior race at the 2011 African Cross Country Championships. She missed the remainder of the season and only returned to regular competition in 2014, the same year she entered the senior ranks. Her first senior medal came at the 2014 African Cross Country Championships, where she was an individual bronze medallist and a team gold medallist. She placed fifth at the Kenyan World Championships trials event, but this earned her selection for both the 5000 m and 10,000 metres events at the 2015 African Games. She excelled at that event, setting an African Games record of 31:24.18, beating compatriot Gladys Chesire. She was also a 5000 m bronze medallist, completing a Kenyan podium sweep with Margaret Chelimo and Rosemary Wanjiru.
