Road race athletes 'vulnerable' in Delhi

Australian walker Nathan Deakes believes athletes competing in road events at this year's Commonwealth Games in Delhi are particularly vulnerable to terrorist attack.

"With us being a road event it probably leaves us a bit more exposed to an incident happening more so than a lot of other events," the reigning Commonwealth Games 20km and 50km walk champion told AAP on Monday.

His comments come after Commonwealth Games security expert Lloyd Bromfield claimed the safety of athletes at the games, which will take place in October, could not be guaranteed.

"In my opinion, it is a dangerous environment, there is no way the Indian authorities can guarantee anything," he told News Limited on the weekend.

"I wish the Commonwealth Games could go ahead and be safe and secure. But to be honest, I've got two sons, I wouldn't have them go there."

But at this early stage Deakes has no intention of pulling out.

"Before everything came out over the weekend and before the reports came out that the English team may not go, we had never thought about the possibility of terrorism or security being a bit of an issue," he said.

"At this stage it is too far out to make a decision about whether to go or not but at this stage it is still something that is definitely on the radar for myself and most of the guys in our squad."

Deakes remembers a similar security scare in the lead up to the 2004 Athens Olympics in which he won a bronze medal in the 20km walk.

"We had a similar issue before Athens where they had a bombing a few months before and there was obviously security problems and security issues before then and everything seemed to go off fine," he said.

With the Winter Olympics in Vancouver to begin on February 12 the Australian Olympic Committee (AOC) says there are no security concerns for that event.

"There is no known security threat to the games in Vancouver that we are aware of but the Foreign Affairs Department is monitoring the situation and they keep us advised of any developments," AOC media director Mike Tancred told AAP.

"None of our athletes have raised any concerns with us."
