Intervals: four workouts to run faster
Alternating fast efforts and recovery is the most effective way to get faster. Four classic sessions, from easiest to hardest.

You don't need to be a born runner. Three runs a week and a little patience put a 5K within reach in a few weeks.
5K is the perfect first distance: long enough to be a real challenge, short enough to train for in a few weeks. The key is to build up gradually and accept walking at first.
Your first runs alternate running and walking, for example one minute of each, repeated for 20 minutes. Each week the running share grows and the walking shrinks, until you can run the whole way.
Start slower than you want to, hold your pace until the third kilometer, then pick it up if you feel like it. Your first 5K has no time goal. Finishing it is the win.
Three runs a week. If a week feels too hard, repeat it before moving on: this plan has no deadline.
A comfortable pair of running shoes that feel good from the first steps is all you need. No watch required at first: your phone can track distance and pace.
Breathe naturally, through your nose and mouth. If you can't talk anymore, slow down. For runs under an hour, drinking before and after is usually enough.
Volta has running workouts from your first easy jog to intervals, and tracks your distance and pace with GPS. You can mix them with strength or mobility in the same week.
Often six to ten weeks with three runs a week. Everyone moves at their own pace.
None. The first goal is to finish it running. Time comes with the second one.
Yes, and it's a good idea. Just keep heavy leg sessions away from your most important runs.

Most of your runs should be at an easy pace. Why aerobic base training matters so much, and how to recognize it without a watch.
