Race Day, Automated: Introducing Race Event Detection
Link to this headingAutomations That Know It's Race Day
We're launching Race Event Detection—a system that lets you create race events and automatically trigger special automations when your activities match them.
Imagine uploading your marathon activity and Activity Craft automatically knows it's race day. Your automation adds "🏁 NYC Marathon", assigns your race shoes, marks it private, and adds a motivational note to the description—all because it detected the race.
No more manual tagging. No more forgetting to assign special gear. Race-specific automations that fire only when they're supposed to.
Link to this headingHow Race Detection Works
The system has three parts working together:
Link to this heading1. Create Race Events
Add your upcoming races to Activity Craft:
- Name: "New York City Marathon" or "Local 5K Fun Run"
- Date: When the race happens
- Type: Choose from 70+ options (5K, 10K, Half Marathon, Marathon, Triathlon, Criterium, etc.)
- Distance: The official race distance
- Location (optional): Add city and coordinates for map display
- Scope: Private (just for you) or Public (share with community)
Create events for your entire race season in minutes. They appear on your calendar, giving you a visual race schedule.
Link to this heading2. Use "Race Detection" Condition
Create an automation with the "Race Detection" condition:
- Event Scope: My Events, Public Events, or All Events
- Smart Matching: Activity Craft checks if an activity matches any event by:
- Matching the date
- Matching the sport type
- Matching the distance (with 5% tolerance for GPS variations)
When all three match, the condition triggers.
Link to this heading3. Apply Race-Specific Actions
Add actions that should happen only on race day:
- Add race name to title: "🏁 [[eventName]]"
- Assign race-specific gear (race shoes, race bike, etc.)
- Mark as private or public based on preference
- Add motivational phrases: "Race day effort! 💪"
- Toggle commute off (races aren't commutes)
- Set AI to generate race-focused descriptions
These actions execute only when the race detection condition matches. Your training runs remain unaffected.
Link to this heading70+ Event Types Supported
We support every common race format:
Running:
- 5K, 10K, 15K, Half Marathon, Marathon, Ultra Marathon (50K, 50 miles, 100K, 100 miles)
- Trail races, Mountain races, Track meets
Cycling:
- Road Race, Criterium, Time Trial, Gran Fondo, Hill Climb
- Gravel races, Cyclocross, MTB XC
Swimming:
- Open Water Swim, Pool Competition
Multisport:
- Sprint Triathlon, Olympic Triathlon, Half Ironman (70.3), Ironman (140.6)
- Duathlon, Aquathlon
If your race type isn't listed, use the closest match—detection works on distance and date.
Link to this headingIntelligent Distance Matching
GPS isn't perfect. Your watch might record 5.17 km for a 5K race, or 42.5 km for a marathon.
Activity Craft uses 5% tolerance when matching distances:
- 5K race (5.0 km) → Matches 4.75 - 5.25 km
- Half Marathon (21.1 km) → Matches 20.0 - 22.2 km
- Marathon (42.2 km) → Matches 40.1 - 44.3 km
This handles GPS drift, course variations, and warm-up/cool-down without manual tweaking.
Link to this headingPerfect for Triathlons
Triathlon detection is especially powerful:
What It Detects:
- Swim leg (1.5 km, 1.9 km, 3.8 km depending on race type)
- Bike leg (40 km, 90 km, 180 km)
- Run leg (10 km, 21.1 km, 42.2 km)
- Transition activities (T1 and T2)
How It Works: Upload your Ironman activities separately:
- 3.8 km swim → Detected as Ironman swim
- 180 km ride → Detected as Ironman bike
- 42.2 km run → Detected as Ironman run
- 150m transitions → Also detected
Your automation adds "🏁 Ironman 70.3 - [Swim/Bike/Run]" to each segment automatically.

Link to this headingMarathon Runner
Setup:
- Creates "Chicago Marathon" event (Marathon, 42.2 km, Oct 13, 2025)
- Creates automation:
- Condition: "Race Detection → My Events"
- Actions:
- Prepend to name: "🏁 [[eventName]] - "
- Assign equipment: "Race Shoes (Nike Vaporfly)"
- Mark as private: Yes
- Add to description: "Race day! All the training paid off 💪"
Result on Race Day:

- Automation fires automatically
- Final name: "🏁 Chicago Marathon - Morning Marathon"
- Race shoes assigned, activity private, motivational note added
Link to this headingWeekly 5K Racer
Setup:
- Creates public 5K events every Saturday at local park
- Creates automation:
- Condition: "Race Detection → Public Events"
- Actions:
- Prepend to name: "🏃 5K Race - "
- Remove from name: "parkrun" (avoid duplication)
- Toggle commute: Off
Result:
- Every Saturday 5K gets tagged automatically
- Community members can subscribe to the same public events
- No manual work required
Link to this headingTriathlete
Setup:
- Creates "Ironman 70.3" event (Half Ironman, Sept 20, 2025)
- Creates automation:
- Condition: "Race Detection → My Events"
- Actions:
- Prepend to name: "🏁 [[eventName]] - "
- Append to description: "Race segment completed! #Ironman703"
Result on Race Day:
- Uploads swim (1.9 km) → Detected, tagged "🏁 Ironman 70.3 - Swim"
- Uploads bike (90 km) → Detected, tagged "🏁 Ironman 70.3 - Bike"
- Uploads run (21.1 km) → Detected, tagged "🏁 Ironman 70.3 - Run"
- All three get the description note automatically
Link to this headingPublic vs. Private Events
Private Events (default):
- Only you can see them
- Only your automations can detect them
- Perfect for personal race calendar
Public Events:
- Visible to all Activity Craft users
- Anyone can create automations that detect them
- Great for popular races (Boston Marathon, local parkruns, cycling centuries)
- Community-driven event database
You choose the scope when creating events. Public events help the community—when you create "NYC Marathon" as public, other runners racing it can use your event in their automations.
Link to this headingCalendar Integration
Race events appear on your calendar with visual indicators:

Step 4: Upload Real Race Activity
- After your race, upload to Strava as usual
- Activity Craft processes automatically
- Check calendar to verify detection and actions
Link to this headingWhat's Next: Public Events
Right now, you need to create each race event manually. But we're planning something better: public events.
The idea is simple: popular races will be available as public events that anyone can use. Instead of everyone creating "Boston Marathon 2026" individually, it exists once as a public event.
This means:
- No manual event creation for popular races
- Just create your automation with "All Events" scope
- If your activity matches a public event, automation runs
- Events are maintained by the community
Creating automations becomes simpler: set your automation to use all events, and it will automatically detect any race you participate in—whether you created it or it's a public event.

Race Event Detection changes how you handle race activities:
Before:
- ❌ Manually add race name to every segment
- ❌ Remember to assign race gear
- ❌ Forget to mark as private/public
- ❌ Inconsistent race activity formatting
After:
- ✅ Race name added automatically to all segments
- ✅ Race gear assigned without thinking
- ✅ Privacy settings apply consistently
- ✅ Professional, consistent race activity formatting
Your races deserve special treatment. Now they get it—automatically.
