Negative Split Calculator

I posted this once before a while back, but just came across it again, and it is so useful: http://www.ridersite.org/SBTraining/PaceCal.php

Makes it easier to plan pacing. Last HM I ran with a pacer, and then sped up after 9 miles or so. Next one doesn't have pacers, so I am really trying to plan. There is nothing better than passing lots of other runners in the last 4 miles!

Thanks for posting that. It will be very helpful!

One "gotcha" to avoid - I just finished a Half and I ran 13.22 miles - which is the same distance for the other 2 HM's that I've done.

The extra distance is important because a 9:09 pace, for example, will get me to 13.1 miles in 2:00:00 but the finish line will be about a minute away (I added 75 seconds in my calculations).

Easiest workaround is to subtract the extra time from finish time and the calculator will account for the extra distance.

this is great, very helpful!

So if I'm running a half that is 8 miles downhill and 5 flat. Do I reverse the negative split times?
