Welcome to track riding / training. I started in 2008 and since then have raced at Hellyer, San Jose, CA, Carson, CA, Trexlertown, PA, Marymoore, Seattle WA, Superdrome, Frisco, TX, San Diego, CA, Anadia Portugal and Aguascalientes, Mexico. And I taught a beginners class at Hellyer.
Track riding, training and racing has a significant execution component due to the small area and high speeds. Hellyer is a 333 meter 23 degrees of banking and is a very easy track to learn and ride. Carson with its 45 degree banking, 250 meter length and Siberian pine surface is much harder to learn to ride and everything happens fast due to the banking and surface. All are doable
IMO, the way to approach track riding, training and racing is to do the beginner sessions and then migrate to structured sessions run by coaches. Once one is comfortable in a structured session going fast with a couple of other riders doing drills, then one is possible ready for a mass start race. One can always do a timed race such as pursuit or other timed race where there is at most one other person on the track on the opposite side. You race in the pole lane against the clock.
