How to Download and Install LiNK for MAC on the NKS Speed Coach



We have released the LiNK software for transferring, viewing and exporting data files from the Training Pack versions of the SpeedCoach GPS Model 2 and SpeedCoach SUP 2.

LiNK for OS X Version 1.23.03 – Download Here!

Note: LiNK is currently compatible with OS X 10.10

We are asking you to download it, start using it, and most importantly, help us prioritize our ongoing development by telling us what features and capabilities you most want us to add.

What can you do with LiNK for OS X?

  • Wirelessly transfer “just go” and workout interval data to Mac for viewing and storage.
  • Export data to charting and analysis programs, such as Excel, via CSV.
  • Export data to FIT file format to enable transfer to third-party websites, such as Endomondo, Strava and any FIT-compatible site. These sites enable you to view your workout or race on detailed maps, share your results with friends or coaches, and even compare your results with others.

Use of LiNK Software Requires Firmware Version 2.04 or Higher

  • Firmware version will be displayed on the splash screen upon start-up of your SpeedCoach.
  • IMPORTANT:  All firmware updates will wipe all current workout data from your SpeedCoach unit. Please transfer your data prior to updating firmware.
  • Note:  If you have purchased a SpeedCoach GPS Model 2 or SpeedCoach SUP 2 without Training Pack you can still upgrade your SpeedCoach to access the workout programming and LiNK data transfer capabilities. Click Here to upgrade
