I had the pleasure to have Jonathan as my coach for the Berlin Marathon. I set myself a pretty tough goal – 03:30. When I received the training schedule I knew the training would be hard. I cursed often but seeing the results and knowing the hard work is paying off was worth it. Jonathan was really caring as he kept asking for feedback and how I felt throughout the training. His feedback was always motivating which made me always looking forward to the next 2 weeks of training. His flexibility and knowledge was needed after an injury and dental surgery which cost us one month of training – 1,5 months before the marathon! Jonathan was still optimistic and adapted to the new situation quickly. And it paid off! Besides his professionalism, Jonathan is really fun to chat with. From the first moment, you can clearly see that he loves what he is doing!
