Percentile

I've been adding times to the online rankings lately, and I have noticed that the 2k seems to be the most popular distance/time ranking. In the Concept2 logbook it lists the percentiles for 2k, basically how your time compares to essentially all other humanly possible erg times. I was wondering if anyone knows of a chart that lists percentiles for other events such as 5k, 30 minutes, etc.. I'm not sure if this topic should be in training, although I began to think about it during my pieces, wondering if I was training as hard as I should and could be comparitivly on each piece. Also, is there a type of formula to figure out where your split should be for distances and times? Such as taking your 2k split, and figuring out what your split should be for, say, a 6k, comparitivly? -Eric Di Bari University at Albany Crew New York

I think the percentile you are talking about is the one that shows where you sit in realtion to others for that distance on time, hence it is only relative to the times currently posted. There is a 'Pace prediction' chart available that someone will no doubt post a link to as I cant remember it at the moment. As to the relativity of one distance to another a lot depends on your strengths and weaknesses, when you last did a test, and where you are at in your training programme. An easy way to do it is to convert your time to watts and use your 2k as a 'benchmark. For me mine are: 500m 158% (of my 2k) 1000m 118% 2000m 100% 5000m 83.8% 6000m 77.9% 30min 75.9% 10k 75.5% 60min 67.6% Obviously some are out of synch with others but it is only really a tool to see where you need to do some extra work .... for me it is developing my aerobic ability.

I think I know what you are looking for... Click on "Ranked Workouts" between "Challenges" and "Profile" while you are in your "Log". Here's what I get for my best category.. 1000M 03:23.3 54 of 159 | 34%

You might find The Nonathlon a useful resource for this as well - it gives you a comparator to what your time 'should' be for each event, based on the best times for that event. Cheers, Paul

To estimate a target split from a known one, a rule of thumb I find useful is "Double the distance, add five seconds to split". So if your 2K split is say 1:45, then a reasonable 4K target would be 1:50, a 1K target would be 1:40, and so on. For odd ratios, like 5K or 6K, the formula equivalent is S = 16.63log(D2/D1). e.g. 16.63log(5K/2K) = 6.6. So a target 5K split would be 1:51.6 if the 2K was 1:45. Just an easy to remember rule of thumb that I find works well for the range of 500 to 10K. Doug
