Lamarth Backyard Ultra

I think we should start with a little history. The original backyard ultra was in 2011 and was invented by Gary "Lazerus Lake" Cantrell and is called the Big Dog's Backyard. But its origins can be traced as far back as 1910! What is a backyard ultra? In simple terms, its a 4.167 mile loop which has to be completed in a one hour time window and then repeated at every hour. Lamarth is a working farm set in the beautiful rolling countryside of Southwest Cornwall. Its comprised of compacted fields and tracks. Backyard Ultras are not for the feint hearted. The distance is 4.167 miles because that will get you to 100 miles in 24 hours. Are you the one to put yourself to the test?
