Say hi to the split time calculator

Stefan Kracht

With today's release the toolset of runverter.io can be called feature complete for now. The last - and my personal favourite - tool in line is the new split time calculator.

The split time calculator is your little assistant to work out a proper race strategy and helps you to keep track of it. You can pick a race distance, your desired finishing time and whether you prefer to run an even pace throughout the entire race or change the speed during the race.

Progress bar

For easier orientation, the splits are divided by a tiny little progressbar indicating how far you have come until this split.

Print it!

The generated splits are very printer friendly. Print it out and tape it to the wristband of your GPS watch to recheck the times on the go. Play a little bit with the zoom in the printer dialog to make it fit to your needed size.

The race predictor has landed

Stefan Kracht

In the last couple of weeks I've been busy to improve the toolset of runverter.io. Here is an overview of the changes from the latest update.

new Tool: race predictor

The race predictor uses a previous race result to estimate an upcomming one. It is based on the peter riegel method which is suitable for runs between 3.5 minutes and 3 hours, 50 minutes. Other race prediction algorithms may be added in the future. I'm also planing to offer the possibility to provide a second reference run to make the fatigue coefficient variable.

add homescreen app support for android devices

Minor changes

  • add flash messages to give context-sensitive user feedback
  • add possibility to delete local data on the imprint page
  • update ember-cli from 2.9.1 to 2.11.0

Introducing runverter.io

Stefan Kracht

The only running calculator you will ever need

What pace do you need for a sub 4 hours marathon? What would your 10 km time be like when you manage to keep up the 4:15 pace from last weeks tempo training? How many kilometers does a 100 mile ultra marathon exactly have?

As a passionate runner you may have asked yourself one of these questions before. With runverter.io I want to give you a simple tool to help you answer all of them.

Why runverter?

There are a lot of tools out there that calculate and convert running metrics back and forth. Some of them are pretty barebones, some of them are very complex. Some of them are easy to understand but hard to use, some are the other way around. And most of them look ugly. 

There is such a big potential to get the most out of it. I wanted something good looking. Something easy to understand but yet as smart and feature rich as possible.

The Toolbelt

These are the current and upcoming tools of runverter.io

Features - running the extra mile

There are a lot of obvious features you will easily discover by yourself but some of them you might only come across as a power user. Here is a quick overview to make sure you don't miss the good stuff.

Smart suggestions

You can quickly populate distance fields with one of the suggested race events. Even time suggestions are available and depend on your selected race distance.

Keyboard controls

Use the up and down keys on input fields to increase or decrease the current value by 1. Combine it with the ctrl key to change the step size to 10.

Expert mode

Enable this mode if you consider yourself an expert. It will hide all labels and descriptions to go for a very minimal appearance.

Detailed decimal place

All values are rounded to two decimals. Hovering over it will reveal more precision.

Cross tool input fields

Every tool is using your most recent data, e.g. if you're using the pace calculator to calculate your marathon pace and switch to the pace converter your recently calculated marathon pace is already prefilled.

Offline support

Runverter is always there for you, even if the internet is gone. It offers full offline support which is perfect for raceday when you want to recheck your pace and the mobile network is overloaded. It remembers you and your data, no account needed. Everything is stored on your device. Just add it to your homescreen and treat it like an app.
