Does it matter if the blood type of marathon registration is wrong?

This is very important. According to the announcement issued by the inquiry marathon, I learned that the blood type was wrong when I registered for the marathon, so I must contact the marathon official to modify it. The blood type is filled in to prevent anemia in time after exercise, so it is related to the wrong blood type when signing up for the marathon. Marathon is a very popular long-distance race in the world, with a total length of 26 miles and 385 yards, which is equivalent to 42. 195 km (or 42. 193 km). There are three kinds of marathons: full marathon, half marathon and quarter marathon.
