Skaters coming for a half hour, an hour, 2 hours, 4 hours, 12 hours, 19.5 hours, 23.99 hours, are more than welcome!! Please come along to skate for your personal goals and as support! Particularly the overnight support hours are always incredibly appreciated.
Consider me IN at Dorney. I have 30 days to prepare...who knows what is possible? I know what I'm capable of, but I have to admit to being a little nervous/excited at my first Ultraskate! _________________ Laura | Proud Practitioner of Karmic Longboarding | http://www.happyskater.org
Great to see you here Laura! We've been doing sessions around Greenlake and just keeping them a little more consistent leading up. Skaters surprise themselves on their personal goals, and no matter what comes, you reflect and learn each time. One really cool thing is often those who come "just" to support often wind up skating much farther than they'd imagined. Mental more than anything!
Sheldon if we can rig up a rollsrolls trailer I'll pull ya along. And I hear you on the rain...we'll be keeping a close watch in the final week.
Rodrigo drop a line when you find a location! Maybe we can get Trevor and others on this one...

On the San Diego velodrome you might have to talk to the Bicycle club that controls the velodrome. Let me know when you will be doing this maybe I will push and do 20 mile plus. But that's about it for me with my ankles. _________________ Terry
I have one question though; how is your distance calculated? by GPS, a set measured route at the location or by some other means?
hey Barry
our logistics when we included an end to end course, was to ride the full length beforehand prior, and mark the end points by GPS. the section we chose was an exact 25 miles, a round trip being 50. so we decided beforehand whether to ride that loop once (50) or twice (100) during the daytime, afterwhich everyone would head up to the Greenlake trail loop.
for ultraskate V, we are going to spend the entire day on the Greenlake loop, for a variety of reasons. primarily because it's a lot easier to have people come and support us any time of day.
our loop is published as being 2.8 miles, and we've been around it so many times using a GPS, coming out with a figure of about the same each time. so for those who are going low tech, I recommend they use a manual LAP COUNTER such as this:
and for those who figure they're going to keep doing nutty things like this, I highly recommend getting a GPS as posted toward the bottom of this thread: http://pavedwave.myfastforum.org/about40.html
personally, I use the Garmin Forerunner 201 or 101 for training, because the battery lasts 10-14 hours total. on the day of something like the Ultraskate, I'll use the 28-hour Garmin GPS60 because there's no need to switch batteries, just synch it up with fresh batteries and start a stopwatch session right at the start line, then don't do anything with it until the entire 24 hours is up. and, I'll be manually clicking laps as well, just to be sure the GPS didn't make any gross miscalculations. the only downside is the GPS60 is a little bulkier.
on a loop track, an independent person counting laps at your "aid station" is best. it is pretty hard to find this person, or set of people, willing to stay and click reliably through the entire night and day, in real life. this is why I go with the double-strategy GPS plus lap counter.
is the Dorney loop pretty close, maybe just a little longer than ours? and about 100x smoother? sure looks like butter from those pics of Erics!!
Thank you for the extra info James, Much appreciated.
I think I will have to check out the battery life on my GPS's, I also like the idea of the lap counter, I have one for counting paces whilst navigating in bad weather, and having more than one system should help iron out any discrepencies at the end of such a long session.
I will let you know what I go with after trying a few things out on Wednesday.
I am not too sure about the length of the curuit at Dorney as Saturday was my first session there, oh and by the way it really is as smooth as butter but ten times more grippy
Yeah we just need to decide on an "exact" figure to calculate our Greenlake loop, as I expect the majority of people will count laps rather than GPS.
Given we have skated our lake course so many times, I believe that number will be 2.85 miles. The GPS varies between 2.8 and 2.9 the majority of the time. That little hundreth of a mile can really add up, when it comes to the total outcome of the day, if one is relying on multiplying lap count by an average mile figure. So I've been trying to find the "most" accurate reading between what the parks department publishes (2.8 miles), and what we actually experience on the trail.
Probably the most accurate way to gauge this, is to rent or hopefully borrow a surveyor's wheel, then walk the outermost edge of the trail once, then walk it once again on the innermost edge of the trail. It would be TOTAL GEEK-dom, but I do see other track people doing this quite often there, when getting ready for 10k--50k races.
It looks like Dorney is almost exactly a 3 mile loop, interesting how close that is to ours. I found a pretty good existing mapping of it here: http://www.gmap-pedometer.com/?r=1678356
Why not ride a bicycle around the lake with a odometer to see how far it around the lake.
I use my car the odometer mileage is pretty close. _________________ Terry
Bike would be quicker, assuming that the odometer is calibrated just right.
I was doing some calculations after someone asked "in order to make 242 miles at Greenlake only, how many laps are required?" -- and it's interesting how that hundreth of a mile affects the laps needed to meet Ted's previous record, i.e.,
242 / 2.85 = 84.9 laps
242 / 2.84 = 85.2 laps
242 / 2.80 = 86.4 laps
I also pecked at this map application, "rode" Greenlake online a couple times, and it comes out closer to a 2.8-mile average. I think there could be a really slight corner-cutting effect when mapping the lines, but it's pretty consistent with everything else.
Yeah....I realize this is all really nit-picky, and as long as we chose any of these figures we're already definitely in the ballpark. You'd think there were thousands of dollars riding on this or something?!
