Hey ProductHunt, Simon here. I'm a trail runner in Switzerland. The thing that broke me was endless excel sheets to build race plan, and inaccurate plans from the existing race planners. I had the whole day planned on a spreadsheet, where to eat, which cutoffs scared me, and none of it was on my watch. Garmin gives you a line on a map and that's it. So I spent the night before adding waypoints by hand, at the end, that didn't match the plan at all. I remember thinking there is no way this is still a manual job in 2026. So, Kliva. It started as a calendar because I couldn't find one that had every race, not just the big ones and always had issues finding all information in one place. Right now it's 31k races in 100+ countries, scraped from official sources, deduped, with aid stations ( for some of them, working actively to increase that offer ) and elevation profiles where I could get them (not everywhere yet, tell me what's missing in your country and I'll go fetch it). Then I bolted the actual planner on top. Pick a race, tell it roughly how you run, and it gives you split times per climb, that's based on tens of thousands of results analyzed, which gel at which km (real products, not grams per hour), caffeine and salt dosed to your weight, and how much margin you have at each cutoff. Three versions of the day, because the plan you make on Tuesday is never the day you get on Saturday. And then the missing piece: a Garmin data field that shows all of it on the wrist. Next aid station, cutoff margin, on plan or not, and a buzz when it's time to eat. Free, in the Connect IQ store. If you don't want another app, there's a FIT download and the aid stations show up as course points. Support to other brands is coming up soon as well. Everything is free for now. I'm one person, there's no funding, just pure passion and engineering. Honest ask: if you run, try it on a race you know and tell me where the pacing is off. And if you have a Garmin, tell me your model and whether the field loads, older watches are tight on memory and I'm chasing that. User base is already growing well organically, already have a few users tried the plans on ultra trail races, feedback is excellent so far.
