It’s a sporting bonanza in the south but the weather isn’t playing its part and we may see some sporting participants gasping.

The Speights Coast to Coast continues in Canterbury today but howling norwesters inland could cause headaches for competitors.

Blustery conditions may hinder a few personal bests although in some cases, the wind could be at their backs as they make their way to Christchurch today.

Heavy, thundery rain in the alps has been falling overnight and is expected to ease later as a front moves up the island.

The first of the runners are expected to arrive in Sumner this afternoon, when a colder southerly is likely to replace very warm conditions across the plains.

The Canterbury Wizards play their one day cricket semi final at QEII today and although the weather may be warm initially, that same southerly with some showers could see a shortened game if they stay around for a prolonged period.

The Crusaders kick off their Super 14 campaign tonight at AMI stadium against their neighbours from the south, the Highlanders.  Cool conditions are likely with a southerly wind and some showers could be hanging about Christchurch at kick off time.
