PERSONAL
BEST
An integrated system that helps
novice runners to run smarter and faster.


How can we help the novice runners to run smarter and better?

How can we create a new value that could consistently benefit runners and evolve with them?

Anew business can help novice runners to perform at increasingly higher levels. The integrated system of AI training and personalized running shoes can enhance their performance along with their daily support. This project was developed in 2017.

Why does this idea matter?
The Marathon Fever in China

Driven by Chinese economic development and rapidly growing middle-class needs to stay fit, Marathon fever is sweeping across China.

“Marathoning” has grown into a massive sport and lucrative opportunity for brands.
The Fast growing rate of marathon in China

According to the Chinese Athletics Association(CAA), the number of hosting road running races in China grew rapidly from 22 (2010) to 328 (2016).

There are 2.8 million runners taking part in these races in 2016, which was 1.3million more than in 2015.
3 main problems prevent inexperienced runners to keep practicing.
Wrong running gait

Inappropriate running gait causes the foot to land too far in front of the knee, allows heel with the ground to generate a significant impact transient and then increases injury risk.
Bad fit running shoes

Everyone's feet are unique.The length, width and arch type is all different. It's hard to find a pair of mass-produced shoes that works for everyone.
Inappropriate training habit

87% of runners lack basic knowledge about long-distance running and never had a systematic training before.
solutions we could offer
Evaluate metrics and level up system

Six evaluation metrics enable runners to understand their currently running habits, discover the invisible problems and take action for the next step.
Customized Digital training insole

Personal Best 3D scans each runner's feet, and then builds a customized digital training insole. The digital sensor collects each runner's data.
Personalized AI training system

Based on the runners' analysis, daily training data and personal goal, Personal Best AI training system offers each runner different classes and keeps evolving with them.
3D printed customized running shoes are based on your own data and evolve with you.
Why does this integrated system make sense?
How does this experience look like?
Let's meet Rui first.
Rui lives in Beijing. He recently got influenced by his friend and started to run. Rui believes that completing a long-distance running could be a personal achievement.
After just several times of practice, Rui was inspired to enter a 5KM race.
Rui started the race at a good pace but gave up after 3km as he felt exhausted.
He got blisters on his feet and felt the pain. He realized that if he wanted to continue running, he would need better training.
Feeling demotivated, he decided to go home, but on his way out he saw a pop-up store called Personal Best. He was attracted by their offer for a free running test and a tailor-made footwear.
He decided to go inside and was welcomed by a running expert.
The expert then provided a free 3D scan of his feet.
The expert gave him a running test.
After trying the training digital insole, Rui put it into his currently running shoes and paired the insole with his smartphone.
By using the tailored training class made by Personal Best, Rui could see his progress in six different sections clearly.
Based on the score, Rui knew in which way he could catch up.
Rui compared his score with other running celebrities and saw how far he was away from them.
Rui upgraded the insole to the premium service. He shared the analysis with one of Personal Best’s real coaches. He connected with the trainer about the analysis and got precise feedback.
Rui received a pair of running shoes that fully customized for him based on his personal performance data.
As long as Rui kept pushing himself to become a better runner, his running shoes kept evolving as well.After Rui finished his first half marathon game, Personal Best reduced the extra cushion and made him the second lighter version running shoes. After Rui wore out his own PB shoes in the full marathon game, a new pair of race version running shoes would be directly shipped to Rui.
