There was disappointment for Colchester twins Daniel and Dominic King at the Race Walking World Cup in Cheboksary in Russia as they missed out on their bid to seal a place in the Great Britain team at the Beijing Olympics.

Neither of the Colchester Harriers athletes managed to improve on their 50-kilometre performances in Dudince in Slovakia at the end of March, with the Olympic A standard of four hours as their ultimate goal.

UK number one, Daniel, had already achieved the Olympic B standard in Dudince, when he came home four minutes 49 seconds over the four-hour mark, while Dominic, who is ranked number two in the UK, was looking to improve on his season's best of 4h 16m 19s, which he set in Slovakia.

However, their Russian experience proved to be an unfruitful one as Daniel was disqualified after suffering from sickness and receiving three cards from the judges, while Dominic came home in 60th - 25m 26s outside his goal.

Daniel had set off with purpose and walked in a large group, passing 5km in 23m 53s in 46th position, with his brother just behind.

Things were on track at the 10km mark as Daniel passed in 47m 11s in 42nd and Dominic was 47th in 47m 38s, both well inside the 48 minutes required for a sub four-hour finish.

However, disaster struck for both athletes, as after 20km, Daniel picked up his first disqualification card from the judges and Dominic began to slip back from the required pace as he passed the same mark in 69th in 1h 37m 06s.

Things were looking even worse by the midway point, with Daniel having sickness, before receiving a second card from the judges and Dominic was beginning to suffer as he passed 30km in 2h 30m 33s.

Daniel was still competing well inside the Olympic A standard, however, unfortunately he was given a final disqualification card at the 38km point.

Dominic, meanwhile, soldiered on, passing 40km in 3h 28m 40s and maintained his from to come home in 60th in 4h 25m 26s.

At the front, roared on by a home crowd in excess of 30,000, Russian Dennis Nizhegorodov took over a minute and a half off Australian Nathan Deakes' World Record to record 3h 34m 14s ahead of compatriot and World 20km Record holder Vladamir Kanaykin.
