a kickboard and line up on either side of the lane and then the other half of you start at one end and you swim through individually, while the swimmers on the outside of the lanes have got the kickboards and they're splashing water at you. They're making waves and they're being a little bit rough with you. Just to get you used to that rough and tumble of being in a triathlon race. That's a good fun one. You've got to be careful depending on who's in there but if you're pretty confident with your swimming and you know each other quite well, then that's a very good way to get used to some choppy water and battling with other people in the water. If you're already a part of our triathlon email newsletter and you're not part of our overall swimming newsletter then you can join that on the right hand side of this website. So just put in your email address and you'll also get those once a week where we give you out swimming tips not specific to triathlon swimming but they're general swimming tips which will help you with your swimming. So you can sign up for those on the right hand side of the website. Thanks for watching this week. Looking forward to seeing you in 2 weeks time because these are fortnightly videos and we'll see you then with some more triathlon tips.
