McDowell Meltdown – Red Loop

  • Green ArrowsSpot Loop (3-miles) – The sport loop will be marked with green arrows and is made up of mostly smooth rolling terrain.
  • Blue ArrowsSport > Tech > Long (10-miles) – The classic Sport to Tech to Long loop takes riders through some of the best trails in the desert.
  • Black ArrowsSport/Tech (5.5-miles) – Complete nearly a full Sport loop, then turn left onto the Tech Loop Connector just before the climb to the parking lot. Drop in on The Ledge (or take the bypass) then a lung busting climb takes to up to T-bone ridge before a nice descent leads you to finish out the loop.
  • Red Arrows Big Loop (33-miles) – The marathon course is a total of 43-miles (one red, one blue) The red loop will head out the sport to tech to long route and turn right onto the connector road to Pemberton. Once at the Pemberton trail, hang a left up to Dixie Mine. Up Dixie Mine, right on Coachwhip back to Pemberton where you will make a left and follow Pemberton almost to the trailhead before turning left onto Scenic. Up and over Scenic takes you back to Pemberton where you will make a left back to the connector road you came out on. Hang a hard right onto the long loop to complete the full red loop. Upon completing one red loop, you will then go out for one Blue (sport>tech>long) for a total of 43-miles (full marathon course GPX file). The cutoff to complete the red loop is 3.5-hrs meaning if it takes longer than 3.5-hrs to complete the red loop, you do not have to go out for a blue lap.
