Competing in the 2013 London Marathon, Gelana was knocked to the ground in a collision with wheelchair racer Josh Cassidy at the 15 km feeding station. Although able to resume, she dropped off the lead pace in the second half of the race and finished in 16th place in a time of 2:36:55 hours. The incident prompted London Marathon organisers to alter starting arrangements for the 2014 edition to allow wheelchair athletes to start ahead of the women's race.[25]
