Tom is taking a break from Kyle this week and we have Kyle's coach Lewis Walker to step in as co-host this week!

Along with the ramblings from Kyle, we review some quick times at the weekend and preview the Nash XC.

Lewis chats about his training and some of the training principles that make a successful runner from 5k's to Ultras.

He also touches on the important role that build up races can have for a spring marathon be it cross country or half marathons. Along with providing the usual results, he adds his view on the vaporfly debate!

Lots of great information and insights - enjoy!!!
