Real World Torque Converter Reliability - youtube

These guys went to Oregon for the 100 mile race with a new TrailMaster Minibike with Torque Converter and they
had to replace the TQ belt twice to finish the race.

So it appears that you can expect 35 or 40 miles when riding hard.

Obviously these TQs were not Comet or GTC brand but I wonder if at least higher quality belts are available in the correct size that might be tougher and last longer ?

Belt is a wear item and for the abuse of 100 miles straight of being pounded on, only changing twice without a failure of the driven with all the dirt is a win in my book.
The heat of repeated laps is not normal usage.
I think you would have had to change belts with Comet or any brand.

I have heard of people killing a belt in heavy dirt and hill climbing and they did no where near even 40 miles.

JMHO, your belt wear may vary
