42 years old (Born on January 01, 1983)
Happy Birthday, Mark! Another year older and still pedaling circles around the rest of us mere mortals. Anyone who can cycle 18,297 miles in just under 195 days clearly deserves a cake big enough to refuel those legendary legs—though we might need an extra candle or two this time!Your epic journey cycling around the globe has inspired countless adventurers (and couch potatoes) alike. May your birthday be filled with fewer saddle sores than usual and more laughs per mile than ever before. Here's hoping you celebrate faster than it takes most people to find their bike helmets!
