Here's an article I wrote for Peak Performance a while back that may help endurance athletes that read this blog.
Basically it looks at whether sprint training methods, such as sprint intervals, and plyometrics can enhance the endurance principally of runners and cyclists, as measured by variables such as performance economy, maximum oxygen uptake (VO2max), and ultimately event performance. (for more from peak performance click here)

Sprinting is obviously a very high-powered activity. During a 100m race around 45-47 strides will be taken by elite males to complete the distance, and the likes of Usain Bolt will be touching nearly 29mph at max speed. Foot contacts will take place in less than 0.09 of a second. It’s therefore not surprising that the fastest men and women spend a great deal of their training time, power training. They use heavy weights, sprint drills, plyometrics and short recovery intervals to improve their velocity and speed endurance. Contrast this with the likes of marathon runners, who even at elite level, will be completing miles in 4.58min, as calculated for 2.10hr marathon, and whose foot contacts will take around 300 milliseconds. With a predominantly aerobic requirement for long endurance events (as opposed to the anaerobic sprinter) it would seem that there would be little reason for employing a sprinter’s short-lived power training techniques. However, there’s a growing body of research that indicates that actually borrowing from the sprinter’s conditioning armoury can boost endurance.
Sprint Interval Training (SIT)
Sprint athletes will, for example, perform runs over 50-500m at intensities from 70-100%. Recoveries will vary in regard to the purpose of the training session. However, 400m sprinters, in particular will often use very short recoveries, running near flat out efforts for 30-45sec in particular, across a number of repetitions and sets. These sessions boost lactate/lactic acid tolerance. It’s this type of training (or more exactly the protocol) that could benefit endurance types.

For a recent assignment for UK athletics magazine Athletics Weekly I was sent to find out how British Rowing uses data to develop its athletes and identify talent pathways. The sport works hand in hand with SAS (the sport's official analytics partner). To promote this partnership and showcase what British Rowing is doing (and do note it is one of Britain's most successful sports) a special talent ID was put on and Morgan Lake (second on the all-time high jump rankings and none other than Olympic long jump champ Greg Rutherford went along to put themselves to the test. 

In the AW article I made a comment about learning from rowing:

Definitely yes, however, our sport is a much larger and diverse one, but I’ve often thought that searching even among our own ranks for a male and female triple jumper (one of the UK’s weakest events, for example, at present) could be an interesting project. There are so many talented sprinters who won’t unfortunately make it to the very top but who might, for example, do so in the triple (it’s not as hard as rowing!). Some basic speed, strength and power tests would be easy to pull together to determine potentiality.
