“Simple, practical and effective, for the coach and for the athlete”
I have coached triathlon for 30 years, waiting for a training app that would actually fit, and none of the many options out there satisfied me. Slek was not one more offer: it was a genuine day-to-day collaboration, moving together towards an app really built around training, planning it and tracking it. Slek aims to be simple, practical and effective, for the coach and for the athlete alike.
Christophe Bastie
Christophe Bastie is as well known for his triathlon career (40 scratch top-10 finishes at Ironman, the fastest French time at an official Ironman triathlon from 2003 to 2006, 23 seasons as a pro) as for his coaching: he has been coaching other athletes since 1997. Since 2006 he has trained many pros at the Multriman training structure. Visit the Multriman website
“Convinced this tool is the right one!”
Over the 30 years I have spent helping a great many runners progress, I have watched training methods evolve, and with them the tools available to runners and their coaches. My many conversations with Slek, along with the testing I ran with the runners I coach, convinced me the tool is right for analysing progression with even more precision, and for reading the effects of training on each runner. That makes it possible to go a step further in tailoring and adapting programmes.

“Really convincing. It is genuinely great!”
I have seen the recent changes and I find the result really convincing. It is genuinely great! Even though I had never used a training platform for any length of time before, everything feels intuitive and simple to me. The way feedback from coaches and users is taken on board is a real strength of Slek.

“Compared with similar apps, […] Slek is simpler”
It is a real asset for coaches: approachable, simple and quick. On the whole, compared with similar apps, I find Slek simpler, and the visual design far nicer to look at

“This tool is formidably effective!”
Slek lets the coach create, edit, plan, analyse and talk with their athletes. This tool is formidably effective, and many parts of the app can be customised, so every coach ends up with something even better suited to their needs. Jan listens to every remark from coaches and athletes: the platform keeps evolving to get closer to what each person needs and to satisfy everyone.
Romain Lieux

“Simple, practical, complete […] I picked the tool up very quickly”
With Slek I found the ideal app to start out in my new role as a coach. Simple, practical and complete, it lets me plan my athletes' training, analyse their completed workouts precisely and see them progress. I am no computer or data specialist, and I picked the tool up very quickly. Six months in, I am completely convinced and happy with it. It has also helped me sharpen the analysis of my own training.

What makes Slek strong? Managing athletes is straightforward, and it is easy to use day to day, for athletes and for coaches alike. It is built in close collaboration with coaches, and you can tell.
