Your body mechanics are different when you sprint vs run? Who knew?

Great answer

They are running faster. Probably twice the speed of you when you run. That changes how you a body works.

And can you quit with all these toe off mechanics obsession threads? This is like the 27th one this year. Looking fast won't make you fast.

Or in other words- I don’t have a clue how they do it, and I am a heelstriker hobby jogger that is good for nothing and wants others to be like me too not knowing or trying to be better at anything

Heel striking is just a result of slower rotation in the leg when landing. Faster you run the faster your leg rotates. The slower you run the slower your leg rotates. I don't understand these runners who think landing forefoot is all that matters when it comes to running form.

Another Let’s Run idiot. Forefoot runners run at all paces on the forefoot. It has nothing to do with your speed. Once the foot is about to hit the ground they stiffen it in order to strike the ground on the ball of the foot. And this happens at no matter what speed you are.

Maximal sprint running velocity was 11.85 m/s for Gay and 11.88 m/s for Powell. For Gay and Powell, step frequency was 4.90 and 4.96 steps/s, respectively, and step length was 2.42 and 2.40 m, respectively. According to Ito et al. (1998), sprint running velocity is not related to maximum thigh angle “high knee”, but the faster the sprint running velocity, the greater the minimum knee angle. The maximum thigh angle for Gay and Powell was comparable at 65° and 70°, and the minimum knee angle for Gay and Powell was 41° and 38°, respectively, and these numbers were similar to the data obtained by Ito et al. (1998). The horizontal distance from the toe at the point of landing to the center of gravity for the two sprinters was 0.31 m, and this number is comparable to that for sprinters who run 100 meters in 11 seconds (Fukuda and Ito, 2004). Therefore, it is not necessarily good to land immediately underneath the center of gravity when landing. In support leg movements, an interesting finding was seen with maximum knee extension velocity for Gay and Powell. During landing, the knee joint of both sprinters always remained bent, and when acceleration force was expressed during the later half of the support phase, the extension velocity had a negative value: -50 degrees/s for Gay and -68 degrees/s for Powell. Training guidance that attempts to increase sprint running velocity by reducing the deceleration associated with landing must be reexamined because the landing distance for Gay and Powell is comparable to that of sprinters who run 100 m in 11 seconds. What is important here is that Gay and Powell continue to bend the knee of the support leg during the support phase, and training guidance that instructs sprinters to actively extend the knee and ankle joints of the support leg must be reevaluated.

People who prance around on there forefoot at a 8 min pace or slower are just wasting energy. I read born to run and started to prance around. All it did was gave me injuries. I switched back to landing on my heel my injuries went away. And, since I'm not wasting energy go up in the air, I actually run faster because I focus on moving forward, not up. Forefoot running is bs.
