I'm running my first ever race tomorrow, a 1500m. So I have no PRs to give.
Here are some of my recent workouts:
2x(4x400m,3 steady (avg ~1'17"), 1 fast (1'10" & 1'13"))
2x(4x200m, 200m walk/jog rec) 5-6 minutes between sets. (30",30",31",32",29",30",31",31"). Very windy though, in an advantageous way, and freezing cold. Not all out, but not far off.
2x600m (1'57",1'55"), 2x400m (1'17", 1'13"), 2x300m(53",55") About 4' between each. Not too hard.
12x400m in ~80s, with equal rest. Quite easy.
10.3 mile run on very hilly course, in around 1 hour 27 minutes, moderately hard.
I've been doing a decent amount of easy runs as well.
Will come back tomorrow and reveal all, I'm just curious because it's my first so I have nothing else to go by.
I wasn't sure I'd get much under 5:00, if under at all, but thinking about it a few 75s strung together doesn't sound too hard, so maybe. Thanks for the help guys (even if it is a bit varying!). Can't see myself hitting 4:20, haha. And I'll definitely finish=P
