Full recovery between intervals to build speed and strength
Is a good way to improve your running speed to run with a full recovery in between intervals ? Iv been reading up on this and this is the suggested training idea:
4 x 400 meters with full recovery in between each 400 meters. 4 x 300 meters with full recovery in between each 300 meters. 4 x 200 meters with full recovery in between each 200 meters. 4 x 100 meters with full recovery in between each 100 meters.
With stretching inbetween to keep loose and so on. So if you do your warm up run, stretching, then go onto the above are you building up strength rather than muscle endurance. Also if you worked by time rather than distance, say after your warm up and stretching doing 4 x 5 mins at a faster speed and totally stopping inbetween (but keeping loose). Would that have the same effect? Any help in this area would be appreciated. Thanks. Sonia
