Our Difference

Focused Personalised Attention

 Clear all your running doubts and filter out general tips that do not apply to you. Your physiology is unique and your training should be too. We’ll help you understand your own body and cater to its needs.

Improve Faster

Quit training that doesn’t work. Our job is to optimise your journey for you and make it more enjoyable. You save time and energy.

Stay Injury-Free

Most runners get injured. Staying injury-free requires personalised attention, self-awareness, and know-how. That’s where we come in.

Trusted by Clients and Partners from


Coach Jing Zhi trains and cares about his athletes in a wholesome manner, not just physically, but mentally and emotionally too. For the lead up to my first SEA Games marathon, he has played a key role in ensuring my everyday well-being.

– Serena Teoh, Singapore national marathoner

I was surprised to see my 100m swim timing reduce by 5 seconds just after one week.

– Chang Chia Jone, Supply Chain Finance Partner, Unilever

I completed my first triathlon and half-ironman in the same year thanks to Second Wind!

– Victor Liew, Co-Founder, Xfers

This club has developed me physically and mentally to prepare for the triathlon and cross-country races that I participate in. Joining this squad has benefitted me and this can be seen from the successes from my past races.

– Zubair, Secondary School Student

Thank you for designing my programme for the Berlin Marathon and helping me achieve a personal best of sub-4 hours.

Most definitely wasn’t the easiest of clients to manage but Jing Zhi figured it out and was as calm as collected as anyone I know, which gave me confidence despite only having trained once a week sometimes.

– Joe Hanney, fitness manager, Core Collective

Thanks so much for the guidance (on running injuries and performance).

– Cindy Ong, financial advisor and top ten Singapore Marathon local finisher
