« on: January 03, 2015, 01:02:33 pm »
I was just curious who here has actually done their 10 laps in 1:35 from the Skills Skating Assessment?   Im a pretty healthy dude...Im pretty good on my skates but dang...10 in 1:35 was a push.    I got 10.5 in 1:35 and damn!!!!!    lol       has anybody gone 11 or more?  is it an instant failure if i wouldnt have gotten my 10?

It's definitely doable. Skating at that pace would get you 31.6 laps in 5 minutes. Speedy yes, but not an unreasonable pace.

I have done 10 in 1:34 and I am 45 y/o, smoke and weigh 195 lbs at 5'7" tall. Not the fittest I have ever been but hanging in there for an old guy. I had a Junior skater do 10 in 1:36 which in turn he did 27 in 4:26.

I have never done more than 10 as it doesn't require that to be recorded.

I can't speak officially, but I can speak with certainty on this.
Nothing on that skills assessment is pass/fail. The whole assessment is a snapshot of your skating abilities to give the Certification panel a good idea of how well you skate, without having seen you skate before.

Believe me when I say that at high level play, that speed (and faster) is likely to come up frequently.

When I went up for Level 3 last year it was important to me to show an improvement over my previous lap time (was something along the lines of of 1:42). Since I don't spend a lot of time skating on the track itself, I asked a fast skater to train with me and give me pointers.

Attacking the turns more aggressively helped me a ton.

This is also all good advice: http://rollerderbyathletics.com/27-laps-test/

There is good information there, with one exception. I would advocate that you skate the diamond exactly the opposite of what is shown in the diagram. That is to say, enter the turns tight and exit wide. Also, your line shouldn't have sharp turns, but more resemble the track boundary. If you do it the way I describe, you fight momentum less and let the track work for you. That means faster laps and less fatigue.

The diamond as shown in the diagram is a better line for a race with other competitors, where you want to set up to pass on the inside.

I just created an account just to reply to this thread.  (I've been lurking for a while, so I'm sure it won't be the only thing I ever post.)

There was a discussion on WindyMan's FB a month or so ago about the most efficient line for skating the 27 in 5, which applies here as well that inspired me to do some math.  This is WAY down in the weeds, but I'll link to the spreadsheet here, just in case anyone is curious.

http://goo.gl/ad9ROR


The "Racing Line" described is the one which takes the shallowest possible turn past the apex - it's more or less the diamond. I don't have a picture.  I also ran the numbers for skating right on the inside line, right on the centerline, and right on the outside.

The results are quite instructive - if you could hold yourself right on the inside line of the track, the 27/5 speed is only 9 mph, compared to 10 on the centerline, and 11 on the diamond.  Lower speed is better, right?  However, as your radius of curvature gets smaller, the force required to hold yourself in the turns goes up.  So from a purely physics standpoint, the way to do a racing lap in minimum time is to determine the absolute tightest line you can hold through the curves, and stay on that. (pretty much just what Major Wood said)

Does any of this math make me a better skater?  Probably not. It might make me a marginally better physicist, however.  :)

I'm super interested in making my trucks loose and riding the inside line now.  8)

Here's a quick diagram to show what I'm trying to explain. My CAD skills outside of AutoCAD need work.

Yeah, there's a guy in my league can do the 10 laps in 1:24 (which is on pace for 11.3 laps in 1:35).  So it's definitely possible to get to 11.

+1 what Wood said above.  It's an assessment, not a test.

Just wanted to step in and back what Wood and Darth have said: it's an assessment. Meaning there is no metric that causes some sort of automatic denial of Certification(1:36 and no Cert for you! That doesn't happen).

10 laps in 1:35 is very achievable if you skate the diamond, do crossovers the entire time and have a good cross over technique. The most frequent reason I've seen people not make their lap time isn't so much endurance as a sloppy or incorrect cross over technique. If your crossovers aren't right then you're putting a lot more effort than necessary into your speed.

sloppy or incorrect cross over technique.

Which creates endurance problems.

I've just recently been back on skates after a two year hiatus and I was afraid of 10 in 1:35. Gave it a try the second night skating and managed 1:38. Mind you that I was winded and felt like dying, but like Sin said and Wood quoted, it's all about proper cross over technique. Question: is anyone still keeping track of who has the all-time record, or did that just fade away?
