Ethiopian Guye Adola and Kenya's world record holder Florence Kiplagat will defend their Airtel Delhi Half Marathon titles on November 29, organisers confirmed on Friday.
The capital city will also have a total of over 25 elite athletes in attendance, with the Ethiopians ruling the roost.
Adola only started running internationally in 2014, and achieved his personal best time in the 2014 edition of ADHM. He won a bronze at the World Half Marathon Championship.
Closing in on his trail are Mosinet Geremew of Ethiopia, who clocked 59:11 minutes at the previous run in the city, his personal best and Jonathan Maiyo of Kenya who came in eighth last year.
If his performance this year in the Mattoni Olomouc and RAK Half Marathons are anything to go by, Maiyo is in it to win it at ADHM 2015.
Former champion Atsedu Tsegay of Ethiopia will be back in the capital this year and is vying to reclaim his title.
