0:00:05 > 0:00:08This is Blue Peter, but mini.
0:00:08 > 0:00:13Expect epic adventures, makes, bakes, badges, pets, presenters,
0:00:13 > 0:00:14and your post.
0:00:14 > 0:00:17We've only got five minutes, so get ready for your Blue Peter adventure.
0:00:19 > 0:00:24The most important thing about any Blue Peter challenge is preparation.
0:00:25 > 0:00:27You've got to know what you're doing,
0:00:27 > 0:00:29and you need the right equipment.
0:00:31 > 0:00:34So when I was told I was taking on roller derby,
0:00:34 > 0:00:36I knew exactly what was needed.
0:00:38 > 0:00:40My snazzy hair rollers.
0:00:41 > 0:00:42Oh, no.
0:00:43 > 0:00:45I've completely got this wrong.
0:00:47 > 0:00:49Roller derby is actually a fast-paced,
0:00:49 > 0:00:51frenetic sport on roller skates.
0:00:53 > 0:00:57Created in America way back in the 1930s,
0:00:57 > 0:01:00it involves players trying to lap each other round the track.
0:01:00 > 0:01:03And it's now becoming popular here.
0:01:03 > 0:01:04So I'm going to give it a go.
0:01:06 > 0:01:10And Emma from the Leeds Roller Dolls is going to help me.
0:01:10 > 0:01:12Or should I call her Tricksy?
0:01:14 > 0:01:16Tricksy, where's that from?
0:01:16 > 0:01:19It's cos I mess around on track, and everybody gets their own name in
0:01:19 > 0:01:22- roller derby.- And do I need to make my own name up for this?
0:01:22 > 0:01:25That would be great if you could, I'm sure the girls will help you.
0:01:25 > 0:01:27OK, that's definitely happening.
0:01:27 > 0:01:30Tricksy has arranged for me to train with the girls' junior team.
0:01:30 > 0:01:31But how do you play roller derby?
0:01:32 > 0:01:36Well, two teams of five people go head-to-head on track.
0:01:36 > 0:01:40They're made up of blockers and jammers.
0:01:40 > 0:01:43Here, the blockers are trying to stop the jammer scoring points by
0:01:43 > 0:01:47skating past them. Staying within the orange lines of the track,
0:01:47 > 0:01:49the jammer has to try and complete a lap.
0:01:49 > 0:01:52And they score points for every person they skate past.
0:01:55 > 0:01:56I've seen how points are scored,
0:01:56 > 0:01:59but I've never seen how you stop people from scoring.
0:01:59 > 0:02:00How do you do that?
0:02:00 > 0:02:03Well, what you have to do is use your body to stop them.
0:02:03 > 0:02:05What we'll be doing today is positional blocking,
0:02:05 > 0:02:07which means I can move in front of you and things,
0:02:07 > 0:02:09but I can't throw a hit into you.
0:02:09 > 0:02:10Do I need any equipment?
0:02:10 > 0:02:12Yes, you need a couple of bits.
0:02:12 > 0:02:14- Two wrist guards. - Yeah, of course, yeah.
0:02:14 > 0:02:16- Thank you.- Elbows.
0:02:16 > 0:02:18- For falling.- Yeah, elbows. Yeah...
0:02:18 > 0:02:20- Kneepads.- And...- For falling.
0:02:20 > 0:02:23Skates. Probably for falling.
0:02:23 > 0:02:24And a helmet.
0:02:24 > 0:02:26- For your head.- Right, OK.
0:02:26 > 0:02:29Thanks, Tricksy. Better get my skates on.
0:02:29 > 0:02:30Ha!
0:02:32 > 0:02:36And now I've got my gear on, I've come up with my name.
0:02:36 > 0:02:39Let me introduce you to R...
0:02:41 > 0:02:42Radical Radzi.
0:02:43 > 0:02:45Ahem.
0:02:45 > 0:02:48Roller derby is a sport that both boys and girls can play,
0:02:48 > 0:02:50but it does help if you can roller skate.
0:02:52 > 0:02:54So I'm going to have a go at some training drills.
0:02:55 > 0:02:57If you're going to play roller derby,
0:02:57 > 0:02:59you need to be able to do our obstacle course.
0:02:59 > 0:03:02- An obstacle course?- Show him, girls.
0:03:04 > 0:03:06What, that? Looks easy.
0:03:10 > 0:03:13OK, it turns out it's not that easy.
0:03:13 > 0:03:14It's fine.
0:03:14 > 0:03:18The next thing we need you to be good at for roller derby is speed.
0:03:18 > 0:03:21- OK.- I was thinking a game of tag?
0:03:21 > 0:03:23Amazing, I love tag.
0:03:23 > 0:03:24OK, bring in the girls.
0:03:24 > 0:03:25What, more?
0:03:25 > 0:03:28# Here come the girls
0:03:29 > 0:03:31# Here come the girls. #
0:03:31 > 0:03:35The aim of this exercise is to try and grab a coloured bib.
0:03:35 > 0:03:39It should get me used to quickly changing direction on skates.
0:03:39 > 0:03:41I'm not very good at this.
0:03:41 > 0:03:43But then...
0:03:43 > 0:03:47Oh! We got a bib!
0:03:47 > 0:03:49Tricksy, you've put me through my paces,
0:03:49 > 0:03:51am I ready to hold my own against these girls?
0:03:51 > 0:03:53Absolutely not.
0:03:53 > 0:03:56OK, I've read between the lines, and I'm going to give it a go anyway.
0:03:56 > 0:03:58Wish me lots of...
0:03:59 > 0:04:03Here we go. One 30-minute game of roller derby.
0:04:03 > 0:04:07I'm going to be the jammer, so it's up to me to skate past the blockers,
0:04:07 > 0:04:10get around the track, and overtake the other team to score points.
0:04:10 > 0:04:12Ha! Doddle.
0:04:14 > 0:04:17Getting past those blockers and staying within the orange line
0:04:17 > 0:04:19limits of the track is actually really hard.
0:04:22 > 0:04:24Every time I go outside of the track...
0:04:24 > 0:04:27Oh, no! ..it's a foul.
0:04:29 > 0:04:30And although I'm a beginner...
0:04:32 > 0:04:34this youth team aren't going easy on me.
0:04:35 > 0:04:37I've scored...
0:04:37 > 0:04:38no points.
0:04:41 > 0:04:44The only way I'm going to get past is with a little trick.
0:04:45 > 0:04:47Your shoelaces are undone.
0:04:49 > 0:04:51I can't believe it worked!
0:04:51 > 0:04:54I've made it past the blockers.
0:04:54 > 0:04:57Now all I need to do is try and get round the track
0:04:57 > 0:04:59and lap the other team to score some points.
0:05:00 > 0:05:02But once again,
0:05:02 > 0:05:03my skating skills let me down
0:05:03 > 0:05:05and I go outside of the orange lines.
0:05:08 > 0:05:10At least it's progress.
0:05:10 > 0:05:13Maybe I can actually score points.
0:05:13 > 0:05:15I just need to stay on the track.
0:05:17 > 0:05:18I'm getting the hang of this, just about.
0:05:18 > 0:05:20It's amazing what you learn with...
0:05:20 > 0:05:21- Blue Peter?- Yes?
0:05:21 > 0:05:23Just to inform you, you've just got seven penalties.
0:05:23 > 0:05:26- OK.- That means you've fouled out, so if you'd like to
0:05:26 > 0:05:28- remove your skates and return to your bench area?- What?
0:05:30 > 0:05:31I'm off.
0:05:32 > 0:05:36I have left the track so many times, I'm out.
0:05:36 > 0:05:39It just goes to show how tough this sport is.
0:05:39 > 0:05:42And although I've absolutely loved having a go at roller derby,
0:05:42 > 0:05:46I'm not sure my team is going to miss Radical Radzi.
0:05:48 > 0:05:50Join in every Thursday on CBBC.
