From the few hundred million (few 100,000,000) sperms in the male's , many of them die on the journey to find the egg, and only an average of about 100 sperms actually reach the fertilization site, where they meet with the ovum.
Upon meeting the ovum, they encounter 2 barriers to break, the corona radiata and the zona pellucida. In layman's terms it would be the walls around the fortress. These walls are not easily penetrable, the first batch of sperms (champion swimmers) that actually reaches the egg usually die off while trying to break down these 2 walls, just like the infantries of the forefront of an army, they usually take the biggest blow before the second or third waves of attacks successfully breaks through the enemies defense.
So, in actual fact, these fastest swimmers that reached the outside of the egg first, die off from the fatigue of swimming so fast and the effort of breaking down these walls, allowing the relatively slower swimmers (us) to have a smoother journey to reach the inside of an egg (the plasma membrane) first, and consequently, fertilizing it
