Issy Alps 50K/100K/100M

The Issy Alps has 4 unique routes to test your endurance. Each of the four routes can be stitched together to form longer routes.

50k starts at Mailbox Peak and ends at Little Si offering roughly 13K of total of elevation climb/loss.

100k  continues off where 50k stops and traverses over Rattlesnake Mountain and Tiger Mountain ending at Tiger mt Highpoint TH.
