Asics Beat the Sun Challenge

Run 148km – over three weeks or all at once!

Challenge Ended: June 21, 2015
June 21st, the longest day of 2015: How will you enjoy it?  

Five international relay teams will spend this day racing around Mont Blanc for the 2015 Asics Beat the Sun Challenge. They’re aiming to cover 148km and 8,350m of climbing in one push, getting every last drop of the long daylight. 

We’re happy to partner with Asics to bring the Beat the Sun Challenge to you. Cover that same 148km (92 miles) any way you like in the three weeks leading up to the summer solstice. Chip away a few kilometers every day, or take on an ultra-run on the year’s longest day – it’s up to you. 

However you beat the sun, track your runs on Strava. All finishers receive a digital finisher’s badge and are eligible to purchase a custom-designed t-shirt.
