Im a firm beleiver in the whole 5km pace is the "golden pace" but i was wondering if any1 knows a formula that can be used to work out someone's 5km potential time from there 3km and 1.5km PB's. This being because i have a 12 year old female that i need to know her 5km pace but im not letting her run anything longer than 4km hard runs because i think shes too old at the moment – therefore not having run a 5km makes it hard to work out her "golden pace"  :wink2:

Her times are:
3km – 10:21
1.5km – 4:48

suggestions of what she could possibly run would be good aswel but if anyone has a formula to work this out from 3km and 1.5km pace i would be very grateful. i know forumlas to work out paces up until 1.5km (400m potential from 200m PB etc) but thats where my knowledge stops :sniff: .obviously there are no 100% accurate formulas as every1 is different but aslong as i have a rough idea i can work the rest out

thx heaps for your time guyz

Using my conversions, I get about 18:15 or so.  Purdy says that she's good for a 17:25 based on her 1500m, and an 18:00 based on 3k, but due to a lack of volume/background they seem a bit untenable.

What formula were you's using if you dont mind me asking.. or was it just a Guesstimate? :Smile:

Well, I am deducing that time based upon how there is a regression in her ability as the distance increases a la the Purdy tables.  Like I said, if you based the 5k on her ability in the 1500m, you'd get 17:25, but you'd only get 18:00 based on 3k.  Due to the fact that she gets lower in the point scales as the distance goes up (very common in young, underdeveloped runners), I guessed it would be even slower than her 3k conversion.
