Yup, I'll be working on my pumping; and agree that it could psyche some of the guys out lol! I'll keep you guys posted on how the race turns out.

And yes Im sure Yandall skogging would really be a sight to see!

The June 1976 skateboarder magazine I bought from the long board grotto has the original Skate tip Chris Yandall penned on skoging. But back then he called it "cut the Jive & jog" or jogging on your board. He was on skinny board and said it will build new mussels and help your switch stance.
I can't believe I own this issue again like I did over 30 years ago.

Well I'm definitely planning to meet up with Yandall and see his wild moves, a winter trip down to SoCal would be awesome, especially when the Northwest skies are gray and the rains are peaking!!

I just posted some thoughts about push vs. pump on another forum and it related to this topic so...recycling those thoughts here:

I find the "dropdeck versus topmount" efficiency arguments to be overblown.   Everyone feels they need a dropped deck because rollsrolls and the skates across america history and everyone else who's been pushing their way around the world is using drop decks.   So the popular logic seems to follow that pushing a drop deck is more efficient.

BUT -- the more you balance and switch between an extremely efficient pump and the still efficient push of a relatively low (4.5"--5") topmount deck, the more you will appreciate that the time you spend NOT pushing, is energy you've got stored up for when you do push.

And on top of that, I'm developing some extremely efficient ways to push UP hill on a topmount, that I used a lot during the RSVP ride to BC from Seattle, which was heavily uphill.

It's like an speedskater's motion on ice, switching push legs from side to side, from every 3--5 pushes, maintaining momentum uphill.   Unlike the straight-legged pushes on a drop deck, your legs always remain a bit more bent at the knees, to keep slightly higher as the topmount requires  (emphasis on slight!)  and you crouch a little more.   But the overall effect is that I keep up fine with guys on their dropdecks on the inclines.   As was mentioned earlier, I guess the only way to really measure efficiency in this regard would be some kind of oxygen input-output measure maybe combined with heart rate monitor to gauge energy expended.   But for now I think deciding how close you are to passing out at the top of the hill can be a good "gut level" science   Very Happy

James that is so freaking Rad that you are going to meet him.  I have so much respect for him.

Just the other day I was watching some of his wild vidoes and I was like "wait a second........O now I get it."

He moves the way he does not for any trick per say he does it because it feels good......

He also makes that one footed stuff look easy.....and it is not. Confused

Hey, that race I mentioned is tomorrow.  I've decided to go with a drop-through deck that I just made last week.  Primarily I made it as a free ride/DH board but I also like its height for pushing. (see image of final set-up below)

I've been doing a bit of skating of the 9km distance over the past 2 weeks, and Im stoked that Ive been able to cut down my time from 28 minutes to 25m45s.  Hopefully it's a competitive time.  

And oh, it looks like rain tomorrow so... any tips? I know I'll have to watch out for maintaining traction on my pushing foot on the wet pavement.  Anything else I should take note of?

EDIT: Just finished that race yesterday. Im happy I did ok actually, did it in under 22minutes and placed in the top 5, and by default offically placed 3rd since there were two fniishers ahead of me that didn't check in at a designated check point. Im stoked about it... And as to how it was run, no one really pumped this race since the course was moderately uphill for the most part. And man were my quads burning up! The turn out was great, about 150+ skaters.  Good fun!  Thanks for the advice again.

why i miss things like this i'm not sure, combination of speed reading and ADHD?

a very belated "Nice work!!!"

I pushed for the first time in months yesterday.  WOW, talk about having to learn the feel of a Dervish at high speed all over again.  RUSTY Confused
