Hi All,

I recently ran (my first) marathon, but far slower than I hoped for, basically because I started off far too fast.

I have constructed a s/sheet to calculate the pace per mile I should be going in order to achieve an average target pace:

I have the following named ranges:
Total_Miles in B2
Variance in B3
Target_Pace in B4
Total_Time in B5

I created what I thought was the perfect formula in column E to start me off at 10% above the target pace, and slowly degrade to -10% by the end. Sadly, the total pace time in E30 differs to the expected value (in B5).

Can you advise please?

Many thanks

Alan
 
Surely you don't take 9:54 to run the final 0.2 miles?

Hi,

The Pace is minutes per mile. In this example I am aiming to run the entire 26.2 miles at an average of 9 minute miles, but want to vary this, starting at 9:00 minus 10% at mile 1, and slowly degrade, mile by mile, until the final mile (or .2 of a mile) is at 9:00 + 10% pace.

[Edit] Ahh, I get you! that's the error! the last .2 miles should be 1.58!

Thanks )

I think Ruddles point was - to get the duration you should be multiplying result by (Dcurrent-Dprior) - last value thus being 0:01:59 (and total of 3:55:48)

It would probably take me 9:54 to run 0.2 miles! :laugh:
