As if swimming almost four kilometres, cycling more than 180 km and then capping it all with a 42.2 km run isn't ridiculous enough, participants in Sunday's Ironman Canada-Ottawa are expected to be sloshing through "yellow rain warning" conditions. The deluge is expected to spread through Sunday morning, with the heaviest rainfall is expected through the evening. The rain conditions are expected to linger through Monday and into Tuesday, the forecasters say. From a sea of carbon fibre bikes and high-tech race shoes to determined athletes chasing the finish line, competitors took on the 226-kilometre (140.6-mile) IRONMAN Canada-Ottawa course through Ottawa on Sunday.
