Alaska race: The 2004 winner of Alaska’s famed 1,000-mile sled-dog race, the Iditarod, won again at age 53 on Tuesday to become the oldest champion, a year after his son became the youngest winner. Mitch Seavey and his team of dogs sprinted across the finish line just 24 minutes ahead of Aliy Zirkle, who was bidding to become the first woman to win the Iditarod since 1990, when Susan Butcher claimed her fourth championship.

Formula One: F1’s postponed flotation could be relaunched later this year, the sport’s commercial supremo Bernie Ecclestone said yesterday. “Last year I thought that the markets were not ready, but now it is getting more likely that there is an opportunity,” the 82-year-old British billionaire told the official formula1.com website ahead of Sunday’s Australian season-opener. Ecclestone said last November that any initial public offering (IPO) was unlikely before 2014. The owners of Formula One had been preparing a $3 billion IPO in Singapore last June but decided to hold off as global markets tumbled.

Basket, NBA: Miami Heat are one win away from becoming just the fourth team in the history of the NBA to enjoy 20 straight victories in a single season. A comfortable 98-81 win over Atlanta Hawks on Tuesday made it win number 19 and after a ‘red-eye’ overnight flight to Philadelphia, the defending champions will be back in action again, taking on the 76ers for number 20. For coach Erik Spoelstra, the winning streak is a topic he avoids in his team-talks as he focuses on drilling good habits into the team before the games that really matter – the play-offs. “I’m not going to bring it up. I haven’t brought it up once yet, the streak,” he said.
