2k in 7:35 ~ 1:53 avg pace. Try the first 750m@ 1:51 and pick it up in the 2nd half if you can, targeting to end with a 1:50-1:50.5 avg pace. (~5:30)<br /><br />

I did not sprint at the beginning or end of the 1.5k.<br /><br />thanks,<br />Hank

Standard running race prediction works like this:<br /><br />T2 = T1 * (D2/D1)^1.0707<br /><br />T2 = 7:35 (1500/2000)^1.0707 = 05:34 or 01:51/500M pace.<br /><br />Good luck. I am intrested to know how close the prediction will be.<br /><br />Bert <br /><br />

A Negative split plan would look something like:<br />500M segments<br />1:48<br />1:47<br />1:46<br />Go for it!<br /><br />You can still put in a good strong start, then just get to pulling the Target split after those 10 strokes are done. You want to be feeling pretty good at 1k, but questioning your own sanity by 1500m, if you are still feeling good at 1500 you could have gone out a bit faster, but there is still time to ramp it up and make a good dent in the total time.<br /><br />Remember, pulling 1:48's in the display can be 1:47.6 to 1:48.5, generally the adrenalin will keep us on the fast side of any target, what the plan is for is to keep you from falling into the trap of "Wow, I'm pulling 5 seconds under target and it feels easy, I'll just keep it going."

Tomorrow's my first race of the year and as long as I'm not in atrial fibrillation (which I go into unpredictably fairly frequently) my goal is to try and break 7min for the first time. I don't know if it's possible for me but the fun is in trying to find out! thanks again for the reply,<br />Hank Greenblatt

My december 2k test was a 6:57 - and I haven't done a all-out test since then. <br />My coach wants me at a 6:45 (1:41.3) by the end of the year.<br /><br />To get a feel for it without killing myself, I have been rowing 1500's at that pace.<br />I have been improving slowly, the first time I couldn't even finish the 1500 at a 1:41.3 avg.<br /><br />Today, however, I finished it at a 1:40.8 avg and with a good deal left in the tank. Tomorrow I think I might try a full 2k at the 1:41.3 -- <br /><br />I'm thinking I'll make it. Monday is the test, and I am typically able to push myself harder with my coach screaming at me and my competition at my heels. <br /><br />What do you guys think?
