They should do one 15.1km.. And hopefully is gets shorter by the year.😁

AMong the methods other than the bicycle with jones ounter, I would say the next best accurate measuring would be Surveyor's wheel followed by Mapometer. GPS should ranked lower in term of accuracy . That is why I feel those organiser who say their onsite survey is to use runners with GPS with measure is wasting time.

Now can see liao..Thanks for the effort to map out the run.

Cannot see, coz you didn't set it for public viewing.

At least this takes some effort. Running or walking with surveyor wheels is no jokes. Most other organizers just get some runners with gps watch for site checking, as good or bad as the reading my own watch . 😂

Thanks for the info. So how is it for Craze Ultra? Got to carry own ration? Can run off course to nearest 7-11?

This run last about the 3 day.how to settle meal logistic? They provide food, or the runners got to settle themsleves? Can halfway run to nearby coffeeshop?

Then I feel Pink Apple using of map my run to map the course may be more accurate.

Don't make sense. On strava, you will have even more samples from different GPS watch for the same race. Variance can be 1km. Why don't average them, if more samples is considered more accurate.

I wonder, how does a pacer check the distance? DO they ruin with a surveyor's wheel?

SO in seems that problem is KPI not meet contractual agreement, likely payment.. They keep on having warehouse house these past few weeks. And they just had the closing down sale of 2XU store at Suntec.

Thanks Yh90 and Beast. Scratched my curiosity itch.

Actually this topic you raised is quite interesting. Just most of our opinions is we don't expect the organiser to do measurement onsite if they are not certified. Now I am curious is whether SCSM iaaf certified is for all distances or just the 42km.

Since the topic touches on course accuracy. Our SCSM is IAAF certified, is it certified for 42km only? or 21km and 10 km are certified too?

So far I think only scsm is certified. So can't expect them to use bicycle and to the measurement on actual course.
