- easy access
- consistently flat
Yes it is nice and flat and you can run faster but it is hard. Running over 50 is a challenge in itself however it does increase when running on harder surfaces like asphalt. It is going to generate more shock to your body than grass or trails. If it can be avoided do it and run on another surface. If it's all you got then make sure you have some good running shoes that can help absorb that shock . You can also learn new running techniques. One of them is Chi-Running. I will be doing a whole multi part series on that subject in the future. If you can't wait you can see it all on Amazon here Chi Running.It is a form of running that really limits injury. It's great for running on pavement as you will lessen the impact jolt on the leg and body. as where there is asphalt there are cars. Always run aware. I will give safety tips on running in the future.
In summary asphalt isn't the best but it is by far the most common and one can learn to run as safely as possible on it . I have run miles on it and do well on it. I prefer it as my easy to go to running surface. Many lakes around these parts have asphalt paths going around them and that is where I do my long runs when possible.
