Tawengwa along with South Africa’s Irvette van Blake were among the 11 participants who failed to finish the race won by Ethiopia’s Tiki Gelana in an Olympic record of 2 hours 23 minutes and seven seconds.
Tawengwa follows in the footsteps of Cuthbert Nyasango who also failed to finish the marathon at the 2008 Olympic Games in Beijing China.
Ironically, Nyasango is one of Zimbabwe’s representatives in the marathon this year, which will be staged in London taking the same route that the women took Saturday.
She also joins the likes of swimmer Kirsty Coventry and rower Micheene Thorncroft who are coming back home without a medal from the global sporting festival.
Tawengwa was in the top 50 after the race had gone past the 15 kilometre mark but dropped out soon after. Prior to the Olympic Games he had been training in Kenya hoping for a better show.
Kenyan Priscah Jeptoo finished in second place with a time of 2 hours 23 minutes and 12 seconds with Russian Tatyana Petrova Arkhipova in third place with a time of 2 hours 23 minutes and 29 seconds. Another Kenyan Mary Keitany was in fourth place with a time of 2 hours 23 minutes and 56 seconds.
