The dirt
North County’s best trail hint — if you know, you know.
Chaparral, granite, and ribbons of singletrack that locals protect like a secret handshake. Trans San Marcos links the systems riders already whisper about — the ones that reward flow, fitness, and a little nerve.
No early course map. No circus. Just the real network, timed your way.
