Looking at the Challenge activity log, Dennis completed the Ultra Challenge last night with an elapsed time of about 23:10, ending with the Black Diamond. Congrats @dennis-s! I look forward to hearing about your experience.
For those of you who don’t know Dennis, he’s a somewhat prolific ultrarunner who’s already completed a number of ultras this year, including the Virgil Crest and Might Mosquito 100s, FL50s, Cayuga Trails 50, Thom B Marathon, and the Morgan Hill Meat Grinder 50.
