There are many reasons to run with a pacer. First of all, they can help you run at the right pace. If you go out too fast in the first half of the race, you can run out of energy quickly and slow down in the second half. Similarly, if you set out to run a slower first half and a faster second half. It can be hard to follow the pace in the end because you’re very time them. With a pacer, you don’t have to think too hard about your pace. You just need to keep up with your pacer.
Marathon pacers do more than that. They can encourage you to keep going when you go through the hardest part of the race. In fact, many marathon runners bring out the best in them by following a pacer.
It’s not easy to become a marathon pacer, you must have experience in running marathons and be able to pace a race correctly.
