They just took off at 8:30 AM local time and covering the 1st km in 4.55, but believe me they’re going to speed up at some point to average close to four minutes at some stages of the race per kilometer. Interesting that the men and women started together. The best women hung on for the 1st km but after the 1st km a big lead group of around 20 walkers detached themselves from the others containing all the favorites.
