Except for cross-country Mexico and the Glamis dunes, the rockcrawling and trails I ran were mostly are 1 mile or less. Rubicon is what 15? and Ducy-Ershim is what 31 miles?
At the recommended break-in it would take 500+ trail runs to break in my front diff. At about 2 trail runs a month or about 24 times a year... hmmm.. I'd be really old by the time my front diff was broken in!!
Gnarls.
