If the weather and his legs are allowing Akani Simbine could clock his 23rd sub-ten second time over 100 metres tomorrow at the 58th Golden Spike, an IAAF World Challenge meeting, in the eastern Czech city of Ostrava. 

Judging by his results over the short sprint so far this season it could be a mere formality. The first time the Tuks based athlete raced over 100 metres this season was at the Diamond League Meeting in Shanghai where he clocked a time of 9.95s.

Although it was not an officially recognised IAAF race, Simbine was even faster over the past weekend winning the 100m during the Adidas Boost Boston Games in 9.92s. It was only the second time this season he raced the 100 metres.  

The Boston Games is a streets athletics event. 

Werner Prinsloo (coach) said Simbine's primary goal in his next three races has to be to run a time faster than his  South African record of 9.89s. 

Earlier this year Prinsloo predicted the gold medal is going to be won at the Championships in Doha in a time of 9.80s or faster that is why it is essential for Simbine to be faster. 

Over the past three years, Simbine has proved to be one of the most consistent international sprinters with his season's best time varying between 9.89s and 9.93s. 

It is an exciting statistic as, according to Prinsloo, it proves that the next real breakthrough is bound to happen in any race. 

"The real tester for us is going to be the London Anniversary Games (20 July). The plan is for him to be at his best. During last year's meeting, Akani ran a season's best time of 9.93s. 

"After this, I will taper his training a bit before we start the final build-up to the World Championships."

The other sprinters to watch tomorrow are Michael Rodgers (USA - season's best 10.00s) and Zhenye Xie (China - season's best 10.02s). The South Africans who will be competing in the 100 metres are Thando Roto (Tuks), Henricho Bruintjies, Simon Magakwe and Thando Dlodlo.

Clarence Munyai is listed to race the 100m and the 200m but will in all probability only compete in the longer sprint. 

According to an IAAF release, Christian Coleman's eagerly anticipated season's debut over 200m will be among the key highlights.

Coleman, who has clocked world leads of 9.86 and 9.85 in the 100m already this season, has indicated that he's aiming to tackle both short sprints at the World Championships. Tomorrow's race will provide an early test for his double ambitions. The 23-year old Coleman has a 19.85 personal best but hasn't raced over the distance in almost two years.

Tapelo Phora (400m) and the Tuks athlete Orazio Cremona (shot put) are the other South Africans who will be competing.
