Just filter out anything that says "road" (though I am planning on trying the SF Century) and you're there! First race is one of the easier: Mid April - Socorro NM. Not that ANY race is easy, but...
I did Socorro, Tierres Torture and Pajarito Punishment last year. Each race was fun and extremely painful, with lackluster results on my part. I should be able to improve on them this year. If not, it might be time to hang up my racing pedals.
Stay around this forum. Many of the races are talked about here, both before and after.
