âThereâs called free circulating DNA, the fetus, some of its DNA gets into the maternal blood and we can actually detect that DNA -- the accuracy of these tests are about 99 percent,â Dr. Abdullah said, âWe can do this test around 10 weeks, so itâs very early in the pregnancy.â.
Daytona International Speedway is 2.5 miles (4 km) long and a 500-mile race requires 200 laps to complete. However, the race is considered official after half its distance (100 laps or 250 miles (400 km)) has been completed.
Beginning runners should start with two to four runs per week at about 20 to 30 minutes (or roughly 2 to 4 miles) per run. You may have heard of the 10 Percent Rule, but a better way to increase your mileage is to run more every second week. This will help your body adapt to your new hobby so you don't get hurt.
