Hello, podcast fan.

Consider this your invite to the UK's biggest podcasting party.

We're heading to Sheffield from the 4th to the 6th of July

for the BBC Sounds Fringe at the Crossed Wires Festival.

We'll be joined by some of the biggest names in podcasting,

including Sarah Cox, Charlie Hedges, Russell Kane,

and some bloke called Greg James doing his radio four show called Rewinder.

You can watch live shows of your favourite podcasts,

and the best part is free.

To book your free tickets,

go to crossedwires.orgive, forward slash fringe.

BBC Sounds, music, radio podcasts.

Music, Radio, podcasts.

Welcome to The Best Things Since Sliced Bread, a podcast from BBC Radio 4.

I'm Greg Foote, and this series is all about separating advertising hype from hard science.

So far, our investigations include the poor purifying abilities of activated charcoal, hand gels protection against the winter bugs and kombucha's effect on your gut

health. Today, we're entering a world of pain, sports pain, to be precise. Are the gels,

creams and sprays promising to relieve it all they're cracked up to be?

Are they the best thing since sliced bread or is it all marketing BS?

Well, joining me to help run them through the evidence mill is three-time Olympic medalist,

Heptathlete Kelly Sutherton.

Thanks for joining me.
