Ive ran negative, positive, and even splits to set new prs or tie old prs so i currently have zero prefference. My pr sits at 1.54.01 and ran that with a 56 and 58 and i felt like i could possibly drop a little more in my kick. Before my next race im worndering if i should try neg, pos, or even split. My previous pr was a neg split (1.55.4, 58, 57ish) and the one before that was even at 1.55.9 (58ish, 58). What does the community think of the perfect 800m racing strategy for pr?
