 Welcome to film my run. My name's Stephen. I'm at the foot of Beachy Head or the climb up to Beachy Head I've just finished doing a 12k run over the South Downs here But that's not the real reason I'm in Eastbourne for that We need to head to the WELKIN Sports and Exercise Physiology labs at Brighton University Based in Eastbourne where I'm going to do some testing. So let's go Every 15 minutes I have to get a blood sample taken I also have to breathe into an oxygen tube and I also have to drink. What is it, 550 mils? 280 mils of some fluid that I have no idea what it is Just got to do this. So I have to rate myself as well. I reckon let's get into 12 now maybe So 12 is somewhere between a fairly light and what is it? Fairly light in what? Somewhat hard. Fairly light and somewhat hard You'll notice if I speed up my cadence, so I'll let my legs go faster Watch how it goes up. 10.9, 11 And that's the speed of the treadmill, 11 So it's like the faster that I move my legs the higher the speed of the stride football Last drink so I've been going for about an hour and a quarter, an hour and 20 minutes I've got another 15 minutes to go. One more drink Right this is Hallam who's carried out the testing today. What have you actually been doing with me? So basically we've been looking at the moderate intensity domain so that's around the lactate threshold That's basically where the point at which he will not increase lactate as he goes So he will not fatigue as quickly so if he stays at that same intensity He should be able to go exercise for around two three four hours potentially We've done an hour and a half to see whether he's going to oxidise more carbohydrates or more fats depending on whether he takes carbohydrate solution or whether he takes liposibos as well and we're also looking at blood glucose to see whether that actually maintains at the same level or in a placebo state it might drop off and that's when you can start feeling weak within a race Have you got any results now that you can see or do you have to do testing to like get the results? Yeah, so you can't give me any results because that'll give away whether I've had actual carbohydrate drink or just a placebo Okay, that's it. So testing at Brighton University over and done with but it's such an absolutely beautiful day I think I'm going to go for a little run on the downs Okay, we've done the testing at Brighton Uni. I just couldn't resist on this lovely day going out for a little bit of a run so we're just going to start and go up this path here and we're going to get to Beachy Head So there's eSpawn behind me. We're only one kilometre in That's Beachy Head Lighthouse below us Right on the edge of the cliff Sometimes you forget how much of a just a sheer drop is just just there to my like six feet to my left So here's an example of the coastal erosion that you get on the Seven Sisters Cliffs This less than a year ago used to be the path up to the Bell to Lighthouse there and very recently all that fell into the sea That is Berlin Gap. I thought I might stop for a coffee there or something That would be 6K so I would have done a little more than I planned but So we've done 6K. I've got my coffee Okay, so that's the Beachy Head Hotel there and we're about a mile from the foot of Beachy Head and the end of the run Here we come down the hill into eSpawn If you've ever done the Beachy Head mountain this is where we finish and that's the view right across eSpawn and a way to Hastings in the distance there And there we are all done 12K finished I'm back where I started at the foot of these steps here and that's me done for the day Thank you very much for watching I hope you found the Work in Sports Lab interesting and my lovely beautiful sunshiney run over the South Downs and Beachy Head Take care till the next time. Bye-bye
