Humans are built for endurance, not speed. We're awful sprinters compared to every other animal. We try to run our races as if they were speed races, but they are not. They're endurance races. Even a marathon, the way it's run now, it's not an endurance contest.
Long runs improve your endurance but shorter intervals improve your speed. They are mutually beneficial for a distance runner. If you do 5k runs it will help your marathon.
I already have natural speed, which I don't need to work on, so in training I've been working more on my endurance.
I don't run after speed. Obviously, it will be better to have some more pace, but I am very well aware that I can't bowl with the speed of 150 kmph. I am working hard on my technique and variations.
Boxing combines, in perfect proportion, strength, speed, and endurance. Normally, most sports are either about one of the three: either about speed or endurance or strength. Boxing combines all three of them. It's really intense.
You must be fast enough - you must have endurance. So you run fast for speed and repeat it many times for endurance.
Intervals and other types of speed work are essential to improve running speed.
I am not trying to bring down the NSA, I am working to improve the NSA. I am still working for the NSA right now. They are the only ones who don't realize it.
Speed is more important than endurance in the decathlon.
Doing the long endurance stuff seems to have given me the strength to sustain the speed. I think my body is just a lot stronger (thanks to the marathon)... By increasing the long runs, I found that does not take anything away from the speed but increases the strength on the track.
I am in limbo, and in limbo there are no races, no prizes, no changes, no chances. There are merely degrees of endurance, and endurance never was my strong point.
I've just been training and working on my speed. I want to be faster, Everyone knows that the more speed you have the more of a threat you can be in the NFL. For me I have been working on my speed and being more explosive. Everyone knows I can get the 10- or 15-yard runs, but I want to have the 60- and 70-yard runs.
I've always been working hard on my speed for the last few years. Obviously I'm not slow, but as a striker, the more speed you have, the better you are.
If you want to be a successful runner, you have to consider everything. It's no good just thinking about endurance and not to develop fine speed.
I am working hard to keep making progress, to always improve.
I am basically working 7 days a week. When I am not eating, sleeping, or working out, I am working on one of projects which I am just damned determined to finish.
