I usually do 100 repetitions between 14-15 seconds with short rest and 12 oz trainers. I think I can run under 13 or at least 13 low in the track with spikes.
My goal it to run sub 1:58 for 800. Do I have enough speed or should I focus in a sub 4 in 1500?
Thanks
Do both! You can run a 9:12 3200 while you are at it. Speed is good, but your base is important for 800 and up.
Go for sub 4 in the 1500, and do not stop until you reach your goal.
Obviously you have enough "speed" for it. A 12.9 per 100 over 800 would be around 1:43. Do you have enough endurance for it is the question you should ask yourself.
