TASMANIA has laid on the mud for this weekend's national cross-country championships at Symmons Plains.
The event will feature about 1000 competitors and heavy rain on Thursday night has transformed conditions.
"When it comes to Symmons, puddles plus puddles equals mud so we're advising runners to bring their spikes," said event manager Richard Welsh.
"The creek isn't overflowing like it was for the all-schools a few years ago, so we've seen it worse, but as it is also notoriously windy here you'd think the typically Tasmanian weather conditions would favour the home- state runners.
"It'll certainly be a shock to the system for those from Queensland and the Northern Territory."
Some 3000 people are expected for the 75th running of an event previously graced by the likes of Lee Troop, Kerryn McCann, Marty Dent, Steve Moneghetti and four-time winner Rob De Castella.
