– Right, today I’m joined by Mark Livesey for a little Tri DIY. Thanks for joining us, Mark. – It’s a pleasure, Mark. Great.
So Mark is a top-level age grouper, he’s a coach. He’s also partner to pro triathelete Caroline Livesey, and founder of Train Xhale. Now, today, we’ve got you here to talk us through your little hack, your tri DIY, your aero race belt. Now talk us through it and why you’ve done it.
– Well, one of the reasons I’m doing it, is there are produced, or commercially produced belts and sleeves for aerodynamics. And it is astounding when I see athletes still having overshoes on, have a helmet that’s aerotested, all the wheels, and they’ll still have a flappy number on the back. – Yes, it’s like the last thing people think about. So, they’ve done all of that fine-tuning, and then it comes to race day, and they just whack this belt on, and they’re wasting valuable watts.
– Yeah, and if you look at the numbers, some studies will suggest, or some numbers will suggest that it’s between five and eight watts. For five hours of riding, that’s quite significant. Like I say– it does astound me that riders still forget about this. So, what I’m gonna show you is a very quick hack.
And it’ll cost you about two Pounds to do. – Awesome. Where do we start, then? – Okay, so all we need is some knicker elastic, so you need to go to your local haberdashery shop, velcro, scissors, a knife, and stationery– sleeve, like so. – Okay, so what’s our first step, then? – So, first thing you need to do is create a loop.
And make sure you measure that around whoever’s waist it’s gonna go around. And make sure it’s not too tight. The thing is– Well, I know this. Have you noticed guys running with these belts around their thighs? – Yes.
So, you’re doing this for your waist. – Yeah, yeah, and it should stay around your waist. It needs to be comfortable. – So this is obviously, once it’s sewn up you can’t get it apart.
So you’re going to have to step into it. – You step into it, or– or what you can do, it’s a good point. What you can do is put velcro on each side, and stitch it on and actually attach it. There is a danger in that velcro releases, though.
But I find just stepping into it like a pair of pants. – Perfect, okay, and next step? – And then, all you do then is with your velcro, you stick it on the inside like so. One on each side, and one in the middle, if you want. And I’ll show you that, in a little bit later.
We have one in the middle, and then on the envelope itself. So you’ll have an envelope like this, and normally the race number is half an A4-sized number, which will fit into this sleeve. Now what you mustn’t do is manipulate the size of that race number, otherwise you get disqualified. So you gotta make sure it fits in there.
So here’s one I’ve done earlier, and it fits in there, and I’ve a little bit more space. I’ve cut that, and then the opposite side of that velcro sits on the inside of the belt. Now, what’s important here is that you give the race belt a little bit of slack, so when you– – That’s when you put it on it stretches, okay. – So when you put it on, it stretches.
And then that velcro bit in the middle will then sit comfortably. And then that’ll sit on your back, like so. The only thing, the other thing you have to do then, is to make sure that this race belt, or the number sits flush with the lower back and the top side of the backside. It’s again with velcro and on your race suit.
So what I’ve done already is, when I position myself on the bike, I’ll put two pieces of velcro on the bottom of my race suit in the TT position, and then at the bottom of the race number, I will stick the opposite side of the velcro on, assume that’s on there. What will happen then is, when you get out, and you put your race number on, it will sit flush on the race suit, like so. – It’ll stop flapping around. – It’ll stop it flapping around.
That’s the whole point is to keep the race number close to the body and it’s aeorodynamic, and to reduce– any air pressure drag that’s developed by that flappy number. And that is your lot, and it will cost you no more than two Euros or two Pounds within the UK. And it takes five minutes to make. – Fantastic.
It’s a great idea. I’m sure many of our viewers will love that. Okay, Mark, you’re all kitted up. Let’s see this in action.
Let’s whack it on. – Thing is really —, already that one’s found its space. There, boom. – Okay, and then obviously, when we come off the bike, we then have to switch the number ’round, so it’s on our front, so just de-attach? – Really easy.
Flick off the velcro, spin it ’round, and it sits nice and comfy. And it actually doesn’t flap around when you’re running, as well, so it doesn’t become an irritant. – All right, Mark, that is awesome, it looks super aero, and I’m sure a lot of our viewers are going to be wanting to make this race belt, and if you’d like to, you can look in the description below for a list of those items that you’ll need.
