Antelope makes dash to the centre of Sudan (5)
I believe the answer is:
eland
'antelope' is the definition.
(eland is a kind of antelope)
'dash to the centre of sudan' is the wordplay.
'dash' becomes 'elan' ('elan' can be a synonym of 'dash').
'to the centre of' says to take the centre.
The central letter of 'sudan' is 'd'.
'elan'+'d'='ELAND'
'makes' acts as a link.
(Other definitions for eland that I've seen before include "African mammal" , "Animal's" , "One browses in the African plain" , "Browser" , "Large spiral-horned African antelope" .)
