 I think it's fair to say I won't be trying any heat training myself as part of this programme. We will return later in the show, though, to see how Phil's got on in his treadmill session. Now, though, there's someone else I want to meet. Dr Jessica Mee, a research fellow at the University of Worcester in England who specialises in the effects of heat. Hi, it's so nice to meet you, Jessica. You well? Yeah, really good. We head through, yeah? Yeah.
