Mumbai-based founder writing about Hyrox racing, pacing and training. Engineer from IIT Delhi and MBA from IIM Calcutta, with more than eight years of operations and growth work at Uber, Zomato and other consumer companies.
Subninety is an independent, data-first look at Hyrox racing: where time is gained and lost across the eight runs and eight stations, how pacing decisions play out in real results, and which training ideas hold up for athletes working towards a sub-90 finish.
Most people call me Pk. My background is in operations and growth, where decisions get made from data rather than anecdote, and that is the lens I bring to racing here.
