NUA vs B.Coach by Brújula Bike: Personal Agent or Coaching App
NUA is the B.Coach alternative for anyone who wants a personal AI agent for athletes that messages them first, not just a coaching app. B.Coach, by Brújula Bike, builds your weekly cycling plan, gives you a daily nutrition guide and proposes changes you confirm. NUA prepares and adapts your training, your food and your routes with your full context and the forecast, sends you reminders, warns you before you ask and learns from you every day. Free trial, no commitment; price depends on your country (see pricing).
B.Coach (Brújula Bike Coach) is the AI cycling coach from Brújula Bike, a Spanish-language cycling publication. According to its site, it builds your weekly plan from your real rides and never changes anything without asking you. It covers road, MTB, gravel, indoor, cyclocross, track and time trial, and you don't need a power meter: without one you train by heart rate or feel. It has iPhone and Android apps, a web dashboard for signing up and chat with the coach in 8 languages.
Let's be fair: B.Coach does some things really well. Look.
What B.Coach does well: its strengths
B.Coach has some genuinely good things. Changes need your confirmation: the coach proposes and you decide with a button. It gives a daily nutrition guide with a calorie target and a carb, protein and fat split based on your training week. It adapts to real life (illness, injury, travel, race week) with proper rest and recovery weeks. It covers many cycling disciplines without requiring a power meter. And behind it is a publication that knows Spanish-speaking riders well.
B.Coach's limitations: where NUA does better
B.Coach is a coaching app that answers when you open it and write. Its site says nothing about routes, weather alerts, reminders or messages that reach you before you ask. It doesn't mention strength work or sleep and HRV data either. And its nutrition is a daily macro target, not an estimate based on what you actually eat. NUA takes the first step: it messages you with the day's session, prepares your route around the forecast, estimates calories and macros from a photo of your plate and warns you when something changes.
Why athletes look for a B.Coach alternative
Many riders don't want to have to remember to open the app. They want someone to message them in the morning with the workout, the weather and what to eat, to remind them about carb loading or checking the bike, and to suggest moving the session if rain is forecast. That's what a personal agent does and a plan app doesn't.
