In 2013 Hayes was awarded the Order of Ikhamanga (silver) by president Jacob Zuma; for "Her courageous and relentless pursuit of excellence and incredible physical endurance". In the run up to the 2016 Summer Paralympics, Hayes took part in two more IPC World Championships. She won a total of four medals, gold in the long jump and silver in the 100 metres in Lyon in 2013 and double gold in the 100 and 200 metre sprints in the 2015 in Doha. Hayes was unable to attempt a second defence of her long jump title, after the T13 event was removed from the schedule for the 2016 Paralympic Games in Rio. Despite this set back she won two silver medals, in the 100 and 200 metre T13 sprints.
