You are not running circles around anyone if you are cutting your hand, broken ribs, and frostbite etc. like mitch and dee dee(there just examples im using cuz they were cited in the article nothing personal: i think this is a fair comment about the older demographic where they at some point become more hands off and outsource a lot of work, depending on the year and musher, to handlers etc). I dont think theres any age restrictions im just saying if yuor not slinging dog waste and feeding dogs all winter but your handlers r: you might not be the best at staying injury free when it comes time to sling yourself across alaska. And if u are coming up with injuries etc: maybe the race needs to build in accountability for this sort of thing at some point to preserve the integrity of it. idk
