2.5 minute rest between each. Was also done on the road but on a very flat road so I don’t think that slowed me down much. Definitely took a solid effort but I wasn’t completely dead or anything after. Previous PB was 16:58 but almost a year ago so wondering if these miles would signify any improvement.
First, you're not mediocre - you're well above that.
Second, you will definitely smash your PB.
But from here, there are unknowns and conjectures.
Were the mile repeats accurately measured (i.e., not just by car odometer...)
2.5 min recovery is pretty quick - did you measure your pulse rate at the end of each rest?
Then -- is the 5k going to be an accurate course? Road race or track? I assume it will be a race, not an individual TT.
My guess is just under 16 minutes, but depending on the variables above, could be 15:50 - 16:10.
Go for it!!
I mapped it out on how far did I run and it was exactly a mile. Maybe it’s .02 off or so but I’d assume it’s pretty accurate. Wanted to go to the track but the track I usually use had some sort of camp going on all over
Since you have already run 16:58, you probably know enough about your training compared to when you ran that. My guess is you are wondering if that workout is indicative of your 5k pace. I think it probably is.
Maybe 16:20. Maybe.
I think 16:25-16:35. If it felt super in control maybe a touch faster. I ran this exact workout 10 days before a 5k PR with about the same distribution between the fastest and slowest rep and was able to average the slowest rep across the entire race and then kick well for a slightly faster than predicted time.
