Over 1,500 runners toed the line and thousands of spectators lined the streets. We were on a narrow road with tall buildings on either side of us. Music was blaring. The announcer was counting down, and a drone flew overhead. The excitement was palpable. And around us we could hear different languages being spoken. Forecast showed 40% to 100% chance of rain all day. It started to drizzle as we waited at the start.
