Gashaw, 22, won the 10-kilometer race with 28:19, his second victory after his 2016 win.
For a large part of the race, he ran behind training partner and friend, Tadesse Worku but overtook in the final stretch.
Gashaw, a member of the Amhara Prisons Club, said he had prepared in a focused way for this race, choosing to stay in his home town of Debre Birhan (altitude 2,840m) and only coming to Addis Ababa in time for the athletes’ COVID-19 pre-race testing on Friday morning.
Gebrselama won the women s race in 32:32. Her victory comes after she narrowly missed out on first place two years ago due to misdirection in the race’s final 200M.
