Smarter than a training log

Analysis that actually helps.

Lasso goes beyond tracking. Every activity, every week, every goal gets intelligent analysis tailored to you and your group.

Personal Pulses

Your personal coach, after every activity.

Every activity gets an AI-generated breakdown: a concise summary, key insights, and actionable recommendations. Lasso knows your history, your routes, and your goals.

  • Summary, Insights & Recommendations: Three layers of analysis after every workout.
  • Same-Route Comparisons: See how you performed vs. your previous efforts on the same course.
  • Goal Progress Tracking: Automatically links activities to your goals and tracks your progress.
  • Private to You: Your personal pulse is yours alone. Only you see your insights and recommendations.

Built for groups

Weekly group intelligence, automated.

Every week, Lasso analyzes your group's activities and generates recaps, comparisons, and a leaderboard scored against each person's own baseline.

Weekly group pulse with superlatives and awards

The Group Pulse

Automated recaps based on hard data.

Lasso computes sport-specific stats, compares them against historical trends, and generates recaps that give kudos (or shade) where it's due.

  • Superlatives & Awards: From "Early Bird" to "The Suffer King."
  • Context Aware: Knows if it was a recovery week or if someone got dropped on the group ride.
  • Head-to-Head: Deep comparisons when group members do similar activities.
"Just 102 ft of gain... and a Suffer 43 says it was more cruise than carnage."

Weekly Leaderboard

Fair competition based on your personal baseline.

Compete on a level playing field. The leaderboard scores you relative to your own historical performance, so consistency and improvement matter more than absolute numbers.

  • Activity Circles: Visualize daily effort with size and color-coded circles showing intensity at a glance.
  • Rank Change Plot: Track how rankings evolve throughout the week with momentum shifts.
  • Real-Time Updates: Rankings recalculate automatically as activities are added throughout the week.

Race analysis with segment commentary and lead changes

Race Analysis

Race day, broken down.

When group members race, Lasso generates a segment-by-segment breakdown with AI commentary. See where leads changed, who faded, and who closed strong.

  • Segment Commentary: AI-generated play-by-play for each phase of the race.
  • Lead Change Detection: Know exactly where positions shifted and why.
  • Pace, HR & Stop Analysis: Deep metrics for every segment of the course.
"Mile 3 is where it unraveled. A 7:02 pace through the hill while the leader held 6:34. The gap opened to 47 seconds and never closed."

Goals

Set goals in plain English.

Type a goal naturally and Lasso figures out the rest. Activities are automatically matched to your goals and progress is tracked over time. Events, habits, wellness targets -- it all works.

  • Natural Language Input: "Run a sub-20 5K by June" or "Ride 3 times a week."
  • Automatic Activity Matching: Lasso links relevant activities to your goals without manual tagging.
  • Progress Tracking: Your pulses reference your goals and celebrate milestones along the way.
