10K Sprint Day 5: Friend v Friend Fitness Challenges

July 12, 2026

It's Day 5 of the 10K Sprint! Today, we are releasing a major engagement driver to the public: Friend v Friend Challenges.

The Purpose

Nothing drives consistency like a healthy dose of competition. Whether it's seeing who can lift the most total volume in a week, complete the most workouts, or eat cleanest, competition pushes us to work harder.

We had a challenge engine built in the backend, but today we officially designed the public interface and launched it for all users to create, join, and compete in custom challenges.

What We Shipped

  1. Custom Challenge Creation: Users can invite friends to challenge pools based on specific fitness metrics: workouts logged, total sets completed, or macro adherence.
  2. Real-time Leaderboards: Integrated live leaderboards showing stack ranks, metrics, and progress bars of all participants.
  3. Automated Reminders: Built notification hooks to nudge friends when they fall behind or when someone completes a workout, fueling friendly banter.
  4. Challenge Feed Integration: Active challenges show up on your social dashboard so you never lose track of where you stand.

The Goal

Releasing challenges turns Alavita into a multiplayer game. It creates a recurring reason to open the app every day, log exercises accurately, and push friends to keep active.

With Day 5 complete, we have shipped five major features in five days. The sprint is on fire!
