From the joy of finishing to the tough moments — read what runners wrote themselves.
“Markings were kind of confusing at the two loops where the 30k and 50k split off.”David Tran faced rain, mud, strong wind and confusing course signs in the Run for Amma 30km. After checking a volunteer's phone map, he returned to cover a missed section and the full distance, finishing officially 2nd.
We translated a short line from each public race report and summarized the experience. Finish times are as stated by the author, and past editions may differ from this year's weather and operations.
