1000 m race - Positive, even or negative splitting?

Don't tr to run "even" on purpose. Hit the first 400m fast, float the next 200m (probably you'll run a second slower) then use whatever you have on the bell and try to beat people.

I find that if you try to run a conservative 400m the next 200m aren't going to be necessarily any faster.

Aiming for 2:30? 58 low, 30, 61.

Aiming for 3:00? 70, 36, 73.

This is generally the pattern for the optimal racing from my observation.

It's very similar to 800m except the pure 1500m runner has a real shot at beating 800/400m runners. A huge positive split (say 5+ for 2nd 500m) is not ideal as well which is what a 400m/800m runner tends to do.

Be prepared to hurt. A lot.

it is a modified 800m

for that, the ideal splits are ~ 0.5s slowing successive 200s

empirical observation/logic indicate the ideal splits for a 1k are slowing by ~ 0.33s

for a 3'00 : 35.33 / 71.00 / 1'47.00 / 2'23.33 / 3'00.00

for a 2'30 : 29.33 / 59.00 / 1'29.00 / 1'59.33 / 2'30.00

for a 2'15 : 26.33 / 53.00 / 1'20.00 / 1'47.31 / 2'15.00

for the 2'11.96WR, the ideal splits shouda been

~ 25.73 / 51.78 / 1'18.18 / 1'44.91 / 2'11.96

Raced the 1,000 a lot in high school, but my pr was only a 2:34 so take this with a grain of salt. If you're racing it indoors it's 5 laps.

If I was going to be leading I would try to run even clips and attack the last 200 with my kick. If it came to states I would try to get out good but not take the lead. Settle in for the first 600, move up during the 800 and then kick as much as I could from there.

Never plan to negative split unless you're treating the race as a workout. You're not gonna run your fastest by going out slow.

Even splitting is hard. It's increasing effort to run the exact same split, taking a lot of precision and body awareness.

Positive splitting is most common but the key is doing it controlled, that's how people typically run your fastest. By going out faster than even split pace, you give yourself room for running slower as the body fatigues and also, if you happen to be feeling good, you can maintain that pace and run faster than expected. I would be more detailed, but I feel this is good enough.

Best of luck

Look up Robbie Andrew's race

I always enjoyed running 1k. I raced it twice, as it is an infrequent menu item at most meets.

When I was a junior in college with incoming PRs of 3:50 and 1:52. I ran 2:25 off of 1:58. I came through about 5 secends off my likely 800m fitness (it was early and indoor). That allowed me to really finish off the race. Two weeks later I ran 4:04 (3:46).

Seven years later, at the end of my outdoor season (4:00 and 3:41 on either side off this 1k race...and had improved my PR to 1;49). I came through 1:52 and finished in 29 (2:21.0). On a better day, should have been able hold pace or close in 28, which was the pace for the first 800.

From my experience, through 800....come in 3-4 seconds slower than your 800m fitness...or 3-4 seconds faster than you'd come through in an ideal paced mile (through 800).

Then hope you can finish it off.

Even/slightly positive.

Ancient evidence from a slightly different event, the 1,000 yard run. Two races in winter '77.

Splits

Race one: 58 quarter mile, 2:00 half mile, 2:17.6 1,000 yards

Race two: 58 quarter mile, 1:58.5 half mile, 2:17.5 1,000 yards

Suggestion: Run the first 600m about even, then start a long push. Don't go too fast too soon.

The most efficient strategy is to drink a bunch of black coffee and listen to some metal music and run balls to the walls. Just sprint as hard as you can and stay relaxed and smooth.

It's essentially an 800m that is run like a mile. You want even splits. In my opinion it is the greatest race in t&f in that it essentially negates the advantage of 400m speed and 1500m ability, it is the perfect common ground between milers and true 4/8 guys, I just wish it was run outdoors. If your goal is sub 2:30, go out in 29.x and just keep tickin.
