Which of these do you think is a better 5k predictor for what I’ll run:
7x1k (2.5 min rest)
4x1600 (2.5 min rest)
Just wondering if one is a bit harder than the other or if I should expect to run at a faster or slower pace than what I ran these intervals at.
7 x 1k is the best one. You are going to be 3/6 seconds faster than your race pace at least but if you have a good mileage you're clear. 1 x 3000 2000 1000 with 4 minutes rest (world-class athletes used this one) or 4 x 1k with 1-minute rest are also great workouts, good luck
