DOHA : WOMEN'S MARATHON STIFLED

DEBILITATING humidity stifles Doha women's marathon. Runners rushed for medical attention during World Athletics Championships.

Women's marathon runners were rushed for medical attention, faces contorted in pain while other competitors hobbled off the track in the inaugural road race of Doha's World Athletics Championships.

Humidity of more than 73 per cent and temperatures of almost 33 degrees Celsius [91 degrees Fahrenheit] dogged the race, especially started at midnight to avoid peak heat, as it meandered along a course on Doha's Corniche coast road.

''You see somebody down on the course and it's just, extremely grounding and scary,'' said Canada's Lyndsay Tessier, 41, who was one of those to finish, coming in ninth.

''That could be you in the next kilometre, the next 500 meters. It was just really scary and intimidating and daunting. So that was enough to hold me back.''

Around two dozen runners in the 68-strong marathon field fell by the wayside as the sweltering conditions took their toll, in a sport which rarely sees drop outs at this level.

Kenya's Ruth Chepngetich won gold when she took the tape after 2 hours 32 minutes and 43 seconds, crediting ''training in a hot area'' of her home country for helping her to tame the elements.

Tessier's fellow competitors filed behind her as she spoke to the media, some held up by their coaches and others too exhausted to stop and speak.

''I'm just really grateful to have finished standing up,'' added Tessier.

The Championship's organisers told race participants that the event's timing could be changed if conditions proved prohibitive but ultimately pressed ahead with the original plan.

Almost all of the runners were saturated with sweat by the halfway point and most ran with bottles as some video camera being used to film the race malfunctioned because of the conditions.

A mild breeze that lapsed the corniche during opening ceremony and fireworks display had dwindled by the end of the race leaving the runners to bear the brunt of the surging humidity. [AFP]
