Yeehaw! Thanks again for coming!

18 last year at Guelph fest! I guess we're going down hill (I blame myself...I didn't set/break any this year. Too much running the fest, not enough juggling).

There was a world record challenge at IJA 2013, too. It looks like a subset of the broken records is available here:

I don't know the total number of records broken there.

I've still got one video left to upload (Sydney MacDonald with 16 min of 4b full reverse fountain), so it should end up as 18 records for WRC at Guelph Fest 2017.

As to previous World Record Challenges...

The first WRC was in 2010 at WJF 5. Prizes were only for surpassing existing duo numbers passing records.

In 2011 there were WRCs at WJF 6 and the IJA festival. The records expanded to solo numbers juggling records in addition to two-person numbers passing (i.e. the records tracked on the Juggling World Records Wikipedia page at that time). The prize for "missing records" was also introduced to encourage jugglers to attempt a flash or better of passing 17 rings or solo force bouncing 11 balls, the only two records considered missing at the time!

WRC 2013 was at the IJA fest in Bowling Green, OH. The records expanded to everything tracked by Juggle Wiki. Missing records were greatly expanded with minimums set for each, based on discussions I had with Alex Lubker. About 28 records were set or broken by a wide range of jugglers, with Thomas Dietz breaking the most.

Then came the WRCs at Guelph Mini-Fest 2016 and Guelph Fest 2017.

Tomorrow another WRC begins at JuggleMIT 2017, so stay tuned...

What you're saying is 28 records in one fest is the one to beat. I'll have to start training for the next time the WRC comes to a fest I'm attending!

Mike Moore - 9/22/2017 14:13 - Vorredner #

Actually, I'll train especially for if you come to the next Guelph fest. It needs more people/publicity! (and I really thank you for helping with that)

I'm not sure that counts as isolation for some reason. I watched Ofek Snir do 7 balls without moving his feet for over 12 minutes at the EJC last year.

The most convincing argument I heard was that the inability to move has a psychological on people. I've found this to be true in my experience.
