adidas Thunder Run is a 24 hour off-road relay race against the clock. Whether you run solo or in a team of 2-8 it'll test your tactics, endurance, speed and team work. It's an exhilarating, rewarding and tiring race with a great atmosphere. You'll find TR24 physically challenging and mentally tough but an experience not to be missed. What to expect: You can set up camp either the night before or the morning of the race to start soaking up the atmosphere. Once you're geared up, your first runner will assemble at the start line at 12pm and when the claxon goes, together you won't finish for 24 hours. The rules: One team member must be on the course at all times during the 24hrs. Runners must complete one full 10km lap before changing over with a team mate but may run 2, 3 or more laps at a time before changeover. The team with the most laps completed when the clock stops after 24hrs will win.
