I've been getting quite a few questions about the latest cyberslalom time I posted so I thought I'd answer them in one place.
The seattle area guys have been running cyberslalom exclusively in a covered parking garage (aka, the batcave). This place is dead flat down the length of the course and quite long. It has a tiny slope perpendicular to the length of the course (probably to prevent water pooling). The surface is textured concrete. Gareth refers to this texture as "Cheese-Grater". This texture isn't ideal setting fast cyberslalom times because these rough texture lines run perpendicular to the course creating a fair bit of rolling resistance.
We have been looking for an outdoor asphalt cyberslalom venue for many months without too much luck. Gotta find a place with good asphalt, dead flat (the need for drainage normally makes this one difficult), long enough to make the entire 174ft course + runout, no car or foot traffic, a place that dries quickly after raining, and a place where cops or security won't care.
This elusive venue has yet to be found so we continue to run at the batcave.
Previously, my best "official" batcave time was 8.58. A few days previous I ran an 8.43x (light breeze aided) and an 8.39x (wind aided) but couldn't post the times due to the wind aid.
Last Friday, a unique opportunity came up to run cyberslalom on a much smoother surface. I work at a place with a huge open assembly building for huge precision automated machines (
www.electroimpact.com). It has a perfectly flat surface that varies probably not more than +/- 1 inch over the entire 300ft length because we test our machines on this surface. When built about 5 years ago, the concrete surface was sealed so it is quite slippery (would have been perfect for cyber if they hadn't done this).
This building is filled with huge, heavy steel machine parts, two enormous horizontal mills, and generally heavy shite. Friday I noticed that they had just shipped a whole bunch of these big machine parts, and that there was a clear section running a good length of the building. I was pacing it off and it was about 175ft but no room for runout. Right when I shrugged it off as too short, someone suggested that I open the huge doors and have the runout into the parking lot (doh!). I spent about 2 hours using the crane to moving heavy stuff & sweeping a cyberslalom isleway.
Drove home very exited (definitely not adhering to the speed limits) any got all my skate gear. After doing a few pumps on the surface I was hesitant because it was quite slippery and I wasn't looking forward to breaking my shoulder for the 3rd time in 1 year. What the hell, I thought I'd set the course and take some times. This opportunity to set a course in this place may never come again.
Took another hour to set the course using a little laser for perfect straightness. The finish line ended up about 4 feet from the garage doors and the runout was into the wet and rain in the parking lot.
First run felt really slow because I was afraid to pump hard due to the slippery surface. 8.85 - very surprising. Next run 8.41 but I hit a cone! I was stoked. For the next 2 1/2 hours I couldn't best that time. The floor was really grimy and oily right at the start box and my push foot would slip a little bit at the initial push. I finally got out the degreaser and cleaned the start box and my push foot shoe.
This foot slip was really hurting me because my first run after cleaning the start box was 8.291 (did a 2 minute victory/rain dance in an empty warehouse at 1:00am). Second run was 8.280. All subsequent runs were slower and I was completely exhausted (and still sore 2 days later) I called it a night at 1:30am.
I had a pc with internet access at the finish line so I could post my fastest times as I completed them. Deluxe.
There are lots of factors for running a fast cyber time. Is a time in the 7's possible? Definitely, but I think it will take a smooth surface with more grip, better conditioning, and a little bit of help with equipment improvement.
I was running the prototype PVDs without the lastest bushings. These trucks don't have as good a rebound as the newer PVD versions and the new bushings are supposed to have really good rebound. Especially noticeable with PVDs was the wheel-to-rider interface feedback. Some runs I would be sliding most of the way down the course, but I could feel the slide immediately and correct for it. I am sure this is due to the lack of a grommet/bushing between the wheels and my feet, damping out the slide feedback. These trucks make me (and my shoulder) feel safer than ever.
My feeling is that there is no better way to improve your pump that practicing cyberslalom. I can feel my strength and reaction time increasing each time out. It also allows a uniform venue to try out new pumping techniques, foot positions, etc. It also forces you to push yourself 100% because the timer doesn't lie and gravity laughs at you.
