Four men who have run under 2 hours and seven minutes, including Deksisa, and five others who have run under 2:09:00, as well as six women who have gone faster than 2:29:00 will be on the start line at the 15th edition of the race offering a top prize of USD 42,000, according to race promoters, Procam International.
Deksisa, whose personal best of 2:06:22, was clocked while finishing second at the 2016 Rotterdam Marathon and ending up third at last October's Toronto Marathon, is the fastest to have entered for the Mumbai Marathon.
Among the prominent Kenyan runners in the elite field are Joshua Kipkorir and Eliud Barngetuny, who were second and third in last year's Mumbai Marathon.
"We have a stronger men's field this year and I think the men's course record of 2:08:35 (set in 2016 by Kenya's Gideon Kipketer), will be under threat," Procam's joint MD Vivek Singh said.

The women's course record of 2:24:33 (set in 2013 by Kenya's Valentine Kipketer) is probably a tougher proposition but far from unbeatable, with the calibre of athletes coming here, he added.
Genemo had a 2017 best of 2:26:06 at the Vienna Marathon and ran under 2:29:00 in her other two marathons last year, including a win in the Ljubljana Marathon in October.
