for example, a session like 6x80m all out with full recovery, would jogging into the reps hurt the effects of the session?
my start is very terrible but my top speed isn’t too bad (for a distance runner)
i assume i could run the reps much faster with a jogging start compared to a standing or block start, but was wondering if i’d lose anything from not having an explosive start
No, the whole idea for distance runners is that spending time at top speed is what matters, which is why distance runners almost exclusively use a flying start for all-out reps.
TBH 80m seems like a long distance for top-speed development, unless you're gradually accelerating the first ~30-40m to your fastest relaxed speed, holding that for as long as you can with form and relaxation--will be 20m or shorter for some distance runners--and then using the rest of the distance for a gradual easing-off.
I suspect the chance of injury may be reduced slightly with a jogging start. That is how we do it. However, the greatest chance of injury for all seems like it would be the high speed part.
Do you want to recruit your explosive fast twitch muscles or not?
yes elaborate
The reason why posters are saying rolling starts are optimum is not that anyone, face to face on bar stools would tell me I am wrong, it is risk reward.
Posters are worried about untrained distance runners exploding off the starting line. Posters are worried about injuries. That concern does have a bit of merit but the best way to recruit fast twitch is an explosive start.
Of course, run 1/4 mile to 2 mile warm-up. Of course do at least three rolling start sprints before exploding off starting line.
You're not going to run faster but you're going to achieve top speed faster with a rolling start. So you'll spend more time at top speed with the rolling start -- more speed endurance. If you're a sprinter you would start from a standing start to practice explosion/acceleration from a dead stop to top speed. That's not really important for a distance runner.
