When inov-8 got in touch with The Running Channel to tell us they’d taken graphene - the strongest material in the world - and used it in the midsole of their brand new ultra shoe, the Trailfly, for a world’s first, we decided to call in reinforcements to test it out.

Watch as Anna sets ultra runner Allie Bailey a tough 40 mile challenge with 4000ft. elevation, across gritty terrain in East Yorkshire.

Peek into Allie’s mind as she takes on this epic challenge and find out what ultra runners really think about when they take on a tough ultra run.
