I don't know what the runner uses to calculate the mileage, but the mobile phone seems to be not accurate.

In fact, daily running, there are dozens of meters of error is harmless! Because we run every day, it is very important to exercise and improve our physical fitness, and feeling is the key. There is no need to care too much about how far we run every day and what the pace is! Sometimes, if we are too persistent about the daily mileage and how many kilometers we have to complete, it is often easy to deviate from our original intention of healthy running and happy exercise, and it is also easy to get hurt!

Usually, the mobile phone uses app, and the watch uses Jiaming f235. Running is a sport, and it is not required to be so accurate. It is best to run according to your physical performance, which is safe and harmless!

At present, you can only record your running mileage, pace and other data in the form of mobile phones and smart watches. Runners are used as a reference for running data, and mobile phone software also has inaccurate data, but this is only a record and reference. I remember when I was studying, I recorded running data on the playground and recorded running results through a stopwatch. As a runner, I care more about the running data, because it is bought by runners with their own steps and sweat.

Running for the purpose of exercise, in fact, does not need to care about the trajectory and rhythm. Jogging for 30-60 minutes at a time is enough exercise on the premise of ensuring that the body is not injured.

I don't think it's necessary. It depends on where you are going. I have experienced mobile apps such as Goo Dong and Yuepao Circle, and my watches include Xiaomi Color Sports Edition and Jiaming 245. I run on the school track, so the distance of a lap is fixed. The recording track of mobile APP is very unstable and the drift rate is relatively high. Xiaomi sports version will be better, but it will drift in some rainy weather. Jiaming 245 has been used until now, with small drift, stable distance trajectory, little influence and the most stable feeling.

I use the marathon world, which is actually quite accurate.

Download "Glug" sports software on your mobile phone. It costs nothing. Very accurate.

Jiaming watch+small bean sprouts for Jiaming running.

Stryd, because this thing calculates speed and distance by airflow, it won't drift. Mobile phones and watches rely on GPS and base stations, so they will drift.
