I looked at the results of the men at the Moscow Marathon out of curiosity. Most run 42 km in 4 hours, and a ten-kilometer dash in 50-55 minutes – well, this is commonly known. But the age distribution is amusing – note how few people under 24 years old even run the ten-kilometer – 8%. In the marathon, 73-year-old Ivan Demonov tackled the distance in 3:45.
