I am looking into redesigning / updating / improving The Running Calculator on www.runningprs.com, so if you have any suggestions please let me know. Thank you!

Not sure how much you want to reveal or how much time you want to put into it, but one way to enrich the training-pace chart could be to add a column on the right with a sample workout at each pace. Thus a 17-minute 5K runner might see 7 x 900m as a sample CV workout; whereas a 14-minute runner might see 8 x 1200m or whatever. Obviously you don't want people to train by cookie-cutter, but they might find it helpful to see one example of a workout  that could be reasonable for someone at their level.

Another idea would be to add a section under the chart with definitions/guidance for each pace. Thus CV might say "Use this pace up to once per week, year-round for development and maintenance of stamina. A 14-minute 5K runner would typically perform W-X minutes of work in a CV-only session; an 18-minute runner might perform Y-Z minutes."

As for redesign, I find the chart pretty easy to read already. I would question whether the hundredths and even tenths of seconds in the workout paces are providing practical guidance; I would guess they're artifacts of the formulas you're using and might best be dropped/rounded.

I think the calculator is great.  The only thing I would add is the mile pace for the equivalent times.  As an example for a 2:43 marathon it has an equivalent 5k time of 17:00.09.  I would like to see the mile pace required for a 17:00 5k or any of the other distances.

Yeah, sigfigs should be representative of the scale of the event.  Hundredths of a second probably aren't very useful for most of us when estimating our marathon time. :)  I'd guess that showing the time rounded to a unit equivalent to about 0.5% of total event time would be appropriate?  That would be like nearest minute for 3:xx marathon, 10s of seconds for HM, sec for 10/5k, tenths for shorter...

That was exactly my first thought, too.  I find myself doing this almost every time: 1) Put in my latest race time; 2) Get equivalent time for next race distance; 3) Convert time to pace.  If the table also had pace (or could toggle between time and pace), then I could read it out directly.

Thanks!

Please, friends, keep the ideas/suggestions coming!

I would also like to have the ability to select distances from a drop down list.  For the marathon I currently have to type in 26.21875 and it would be nice to have the option to select or manually enter a value.

Also add a column that would have HR %'s for training pace.  What would the HR % ranges be for Easy Runs, Tempos, CV, etc....
