(CNN) -- When the 2010 FIFA World Cup kicks off on Friday, 18,000 specially trained volunteers will be on hand to help South Africa host football's biggest competition.
Almost 68,000 people from 170 countries applied to be volunteers at the huge event, with the application deadline closing more than 10 months ago.
Applicants were screened and then interviewed before the number was whittled down to 18,000 earlier this year.
The oldest volunteer is 79-year-old Daya Amrit, from Nelson Mandela Bay, who even missed his 60th wedding anniversary to take part in volunteer training.
Most major sporting events favor volunteers from their own patch because local knowledge is invaluable during big tournaments. But some events are on such a large scale that overseas nationals are also welcome to apply.
Years of planning goes into major sporting events so, if you are thinking of volunteering, decide well in advance.
With preparations for this year's event well underway, football enthusiasts will now have to wait until Brazil next hosts the next world cup in 2014 if they wish to volunteer.
In the meantime, here are eight up-and-coming sporting events looking for volunteers.
1. U.S. Open Championship, Pebble Beach, California
Golfing enthusiasts could do worse than spending a week of their time helping at the U.S. Open Championship. This year it runs from June 14-20, 2010.
Thousands of volunteers serve as marshals, assist with scoring and give information to spectators. Volunteers at most major sporting events are given their uniform for free but at the U.S. Open you must pay around $165.
The upside is you get a pass allowing you to enter the venue for free for the duration of the tournament even when you are not working.
