Hammerhead has built Karoo on the most flexible software stack possible. This allows any developer to bring value to our platform. Our goal is to be nimble with software releases and build services that cyclists want. Our customers will be a part of making this paradigm a reality, below are some of the ideas that we are currently designing
Build custom workout profiles with alerts and specific heart rate, power or pace goals, link them to routes, and share them with friends.
|Intervals||Easily build interval workouts or choose from presets designed by coaches|
See strava segments while route-planning. Add segments to your route and race them with real-time feedback.
|Live-tracking||Live location and sensor data can be shared with anyone through a URL.|
|Group Tracking||Share location, meetup times and courses to friends on your ride.|
Get a weather forecast pre-ride, wind data on the route and a head’s up for rain. Post-ride wind, power and speed data is correlated to give you a better understanding of your training session.
A whole new standard for training planning, workouts are preloaded on your bike, if you miss one the plan adjusts. Integrate your indoor and outdoor training data.
|Ride leader tools||
Visualize the heart-rate and power output of everyone in your ride group. Get instant feedback on the relative strain of your team.
Find ride groups and training friends in your city, match with cyclists at your level and make group rides easier.
