Show HN: Personalized Triathlon Pace Calculator with 150 Events

jfess•1h ago

Hi HN, I built pacecalculator.io to help triathletes do two things: plan their race day and optimize their training.

You can calculate your pace and finish times for over 150 built-in events. Then, you can dial in your training with personalized FTP, CSS, and LT-Pace calculations.

I used Angular, Node.js and MongoDB.

I would love to hear your thoughts and feedback. Every suggestion helps me make the tool better. Let me know what you think!
