Argument for pushing…the deck does not function as a machine; specifically it offers no mechanical advantage. Pushing is a pure rolling motion where the board is used only for balance and steering. The deck is passive and along for the ride. Elegant.
Argument for pumping….the deck gets used to propel the rider. The truck gets used as a lever, a machine. Leverage of the rider pumping the board gets turned into a resulting force that propels. For pumping, the trucks are actually used to give leverage and a mechanical advantage. Kind of like gearing on a bike.
To me, this mechanically separates the disciplines of pushing and pumping.
Based on this, it seems that pumpers may have a mechanical advantage over pushers…but I hope I am wrong, and I hope that a pusher breaks the 3 minute mile first.
great stuff Mark! we were hoping to pull off a "Dual Mile" pursuit race at the Velodrome but it was the week after Ditch Slap -- the main contenders were pretty cooked, not to mention it was the same day as the 7-mile Seattle Pusher, haha. so we're hoping to reschedule and clock times some time this summer.
PW do you have any data comparing running the mile in a straight line as opposed to doing it on a track?
I've been wanting to do this for quite awhile but about the only road I have that's flat enough and long enough is fairly heavily traveled (and high speed at that). However I can do it on a track but I have a feeling it would give a whole different set of numbers compared to running a straight line.

only my own times, which showed about a 13-second improvement on a straight course (the average of two straight miles versus one loop-tracked mile.) i'm hoping we'll have a lot more data to add later this summer when the P-town heavies come up for a Miler event.
it's hard to conclude from that small amount of data that it was the course and not a variety of other factors. i think pumping around a loop track can be a lot easier than having to push it -- since pushing all-out on a turn isn't the easiest thing to do, but in the end I prefer all-out straights. it just makes the task a little harder to have to run it twice.
A friend of mine challenged me to a head to head runner vs skater mile. He runs a 5:10. Another friend jumped in and challenged me to a 100 meter runner vs skater dash. This should be interesting.
We just had the central park race, Kaspar, and Corey did the 8 miles in 21 min. That's about 2.36 min per mile...right?
hopefully you guys can make it to Portland sometime and take on Robin McGuirk?! i don't know how fast his Portland Pusher times are because Josh didn't post 'em, but his Annie Ross (8.5-mile, always the same course, with downhills) times were
2006 - 28:04
2007 - 26:18
2008 - 25:11
the last Portland Pusher is this year, August 10th.
the difference with these times and the Cyber Mile is with the Mile, we're striving to attain a regulation, reproducible course, no matter where your location in the world.
On the other hand, the Central Park and Annie Ross races can be tracked just like marathons, where each city has it's own "record" time for a given distance and given course, which is a standard benchmark established in that city for other guys to travel there and try to beat. Not like we're trying to be competitive or anything

It's such a cool part of skateboarding...I started Earthwing just to win the Broadway Bomb. In the beginning it was just balsawood /carbon sprinting decks over 10 years ago. I love that. Lighter, lower, faster...just keep one foot on the deck, and push switch too.

yeah, i think you and Robin are living in parallel universes... the portland push races are what's been helping him evolve his craft as well with EastsideLongboards --he usually rides this "drop kick" and ollies over stuff like railroad tracks

now that looks fun!

The other day, Thane from Griffin boards and I got to skate the san diego
velodrome. It's 333.3 meters around, 5 laps/mile.
I got timed by one of the cyclists there on his GPS,
my lap time was 54.25 seconds. All pumping, no pushing,
on my 31.5" Slalom SL, not an optimal flatland LDP setup.
I can't wait to try it on my LDP.
So that would make it a 4.541 minute mile for me...
A 3 minute mile is insane....

Yes I'd like to do this and add more data for you James. Its just a matter of the right time and place which seems to have not lined up yet. Another comparable record is the Cross Town race at Ditch Slap in Alburquerque. The best time is held for this 8.5 mile course by local Ryan Ricker is 21:06 I believe. And I won it last May with a time of 21:20. I'll see if I can get a list of times from TSR of previous winners like Will Brunson who was only a hundred of a second behind me. Hands down the closest win I've ever had at a push race, that guy drove me to pure euphoria as I barely was able to hold him off. I did have to wait about 10 seconds somewhere in the middle for him to catch up and tell me where to go since I didn't know the course, but thats part of the race!
Well I do hope we can arrange a time for David, Casey, and I to do the mile, would be interesting to compare times...and yea the DropKick rules! It has gotten me through the gnarliest of obstacles at high speed when others had to jump off or slow down, ha ha!
