By now you should know that Nike has set to run a sub 2 hour marathon.

You should know that the three athletes that are going to attempt this feat are Eliud Kipchoge, Zersenay Tadese and Lelisa Desisa.

You should know the shoes they will be using while running this marathon.

Last, you should know that the marathon they will be running is not an official, sanctioned one – but a closed event that will take place at the Monza racing circuit close to Milan, Italy.

What you didn’t know yet, was the date of the attempt. And to be honest, it’s much closer than I expected.

As you read in the title of this article, Nike’s athletes will attempt the sub 2 hour marathon on May 6th through 8th 2017. Less than a month from now.

Why a three day window

So – why do they need 3 days for an event that they plan to last less than 2 hours?

Nike needs perfect weather conditions for the attempt to be successful. According to Runners’ World, the historical weather conditions for Monza in this period are ideal: average low temperatures of 54F, low humidity, little wind and cloud cover.

But in order to be sure these conditions will all present themselves at the same time, a three day window is necessary.

Nike estimates that there’s a 90% chance that the perfect weather day will present itself within these three dates.

Can I go there and see it?

Do you want to go to Monza next month to witness the attempt? Nike in partnership with AirBnb has made 10 spots available for 10 lucky runners. Here is where to participate.

What do you think?

So, less than one month from the event – how do you feel about it ?

Will Nike break the 2 hour barrier? Which of their three runners will be the fastest?

What do you think of this event being non-official, run in perfect conditions ? And what about adidas, who also has the same goal?
