Hey look...someone that isn't from Richmond and something that actually applies to the thread...... odd.To reply about something that is actually important to RACING at Massanutten.....Yes the top section of the course is well known for pinch flats. It has many lines and some of them are fast...if you dont flat. I was able to ride a couple of practice runs with some pros, and they said that they were running like 30-35 psi!! I would reccomend Maxxis, dual plys...forget Kenda, and WTB, the sidewalls are too thin for the top section, at least to try out all the lines that are there.
Hope this helps...u did ask a question about riding...and this is RIDEmonkey.....It is a good race super fun, non scary track, that u can always tell what, if anything you've done in the off-season has worked...
