Training load & goal tracking in Overview 🚀

We’ve added new blocks to Overview to help runners better understand their training and track progress at a glance. Here’s an Overview of what’s available for runners.

🏃‍♂️ All activities

See how much time you spent on different types of training during the week (running, strength, cycling, etc.). All running activities are summarised into total running time.

📈 Training load (Runner plan)

Compare your recent running volume with your long-term baseline to understand how your load is changing and adjust before overdoing it.

Subscribed runners can see:

  • Total running distance over the last 6 months and how it compares to the previous 6 months

  • Average weekly running volume (last 6 months vs last 2 weeks)

  • Whether training load is increasing or decreasing - if the recent 2-week average weekly running volume is higher than your 6-month average, your run training load is increasing; if it’s lower, your load is decreasing

  • Training load on a 1–5 scale

    • 1–2: lower than usual

    • 3: in line with normal training

    • 4–5: higher than usual

💡 To improve performance, training load should generally trend toward 4–5 but increases should be gradual and balanced with recovery.

🎯 Goal progression (Runner plan)

Track progress toward weekly and/ or monthly running goals and see how much you’ve already run.

  • Shown only if a weekly or monthly goal is set

  • If at least one of the goals is set, running completion is tracked automatically

📅 Today’s plan

See the training planned for today:

  • Up to the last 2 planned activities are shown

  • If no activities are planned for today, the block is hidden

  • You can mark the plan completed by accessing it straight from Today’s plan

  • NB! Training load and goal progression blocks are currently not available for coaches who also track their own runs in KULG. The users who have been given access to data, do not have access to the Overview page of their runners.

🛠 Other improvements & fixes

  • Resting HR decreases in the Recovery block are now shown in green (positive trend)

  • Fixed activity tag adding in Overview and Plans

  • Goal setting now works even if commas are used

  • Improved time zone handling for planned activities

New

Fixed

We’ve released the first version of Overview 🚀, which will become the new landing page for runners when opening the KULG app.

Overview 🏠

  • Overview is currently available for athletes (and coaches tracking their own activities)

  • Data is generated for the current week. Use the arrows next to the week number to navigate to previous or next weeks.

  • For custom date ranges and more detailed graphs, head to the Dashboard.

  • More blocks and features will be added soon, but here’s what runners can see on Overview today:

💡 Latest insights at a glance

  • Now runners can see the most recent generated insight (including the AI insights) directly on the Overview. The latest insight remains visible until it is replaced by a new one. All inisghts are saved in the Insights’ list that you can find in the header.

📊 Running overview

  • Get a clear weekly snapshot of the last 8 weeks of your running performance on a graph with focus on key metrics. You can tap on a specific week on the graph to see how the numbers change for that particular week without having to go to the next week. The graph visualises the weekly distance and HR vs speed, or how your aerobic fitness improves (the higher the number, the better).

  • As a new development, we now also indicate the weekly change, so you can see how the key metrics have changed. The key metrics also include high intensity from your runs and it’s proportion to all runs (intensity %) and elevation gain.

🛌 Recovery overview

  • Track key weekly recovery signals and how they change at a glance: HRV, resting heart rate, sleep score and feeling.

🏃 Recent activity snapshot

  • View and edit your latest 2 activities directly on the Overview. Go to the Activities list if you need to see more of your activities.


Other things we added and fixed

  • We added campaign details on the Billing page. Subscribe to the KULG Annual Runner plan before January 31 and get 40% off: €53.99 instead of €89.99.

  • We added race events under Plans nad goals if your location is Estonia Under Settings » Account.

  • Resolved an issue where the first week of the month appeared twice in weekly interval charts.

  • Fixed a problem where users with access couldn’t see full activity details for distance-related activities.

  • Resolved an issue where runners and coaches in different time zones saw planned activities at different times. Note: This applies to new activities or existing activities that are saved again.

KULG iOS App is now live 🎉

  • We made small updates to the KULG mobile version to send the iOS app to review. The free KULG iOS companion app is now live on Apple App Store 🚀 Download the iOS app.

Blocked activity sync resolved

  • We fixed the issue that blocked activity sync from Garmin and Strava and manual activity saving in KULG, as well as some other operations on Dec 26 (UTC 13:30) - Dec 28 (UTC 12:05).

  • We resynced the Strava activities and the Garmin activities for users who have enabled the historical data load permission in Garmin Connect (NB! by default, it is off in Garmin).

  • We also made an important logic update regarding resyncing data from Garmin and Strava:

Once the activity is synced to KULG, any change that you may do on the same activity in Strava or Garmin (e.g. add a comment, image, or edit the activity details), will not overwrite the data in KULG. This is important to prevent users from accidentally overwriting their data in KULG.

December 27th, 2025

Fixed

On Dec 26 (UTC 13:30) - Dec 28 (UTC 12:05), activity sync from Garmin and Strava and manual activity saving in KULG, as well as some other operations, were temporarily blocked. The issue was caused by infrastructure issues and has now been resolved.

Please note that your training within this time frame may not be synced - we were able to resync Strava activities and Garmin activities for users who have enabled the historical data load permission in Garmin (NB! by default, it is off).

We are sorry for the inconvenience!

AI Insights are live on the Runner plan! 🚀

We’re excited to bring weekly and monthly AI insights to customers on the Runner plan! Insights appear at the start of a new week or month, providing a summary of your training and a personalised tip to guide your next week or month. Quarterly and annual insights will follow.

Our AI uses all the information you’ve added to KULG, so the more you track, the more personalised your insights become. Here’s what’s considered:

  • Training data: activities data, notes, tags, perceived effort, and feeling

  • Recovery data: HRV, resting heart rate, sleep quality, readiness and sleep hours from Oura, and more

  • Long-term goals & experience level: set during onboarding

  • Physiological data: age, sex, height, weight, etc. set in Settings » Account

AI insights appear alongside other KULG pattern detection insights in the app header under the loudspeaker icon. New insights are marked with a blue dot.

All KULG insights are private - visible only to you as a runner. They are not shared with other runners or coaches, even if you’ve granted them access to your data.

Our AI follows science-based training principles we’ve collected in our knowledge base, ensuring your guidance supports sustainable progress.

Note: We’re continuously refining AI insights to make them smarter. You can help by leaving feedback through the in-app chat widget.

Other improvements and fixes

  • Activity-specific fields: Strength, Crossfit, Yoga, Pilates, Climbing, and Surf activities and plans now show only the fields relevant to that type.

  • Running race detection fix: We now consider average pace, distance, and HR zones to classify running races more accurately.

  • Profile and Settings updates: Landscape profile images display correctly, and the Settings views have been improved for easier use.

  • Custom time frame navigation: On mobile, arrows are hidden when using a custom time frame to clarify that quick navigation is only available for predefined periods (This Week, This Month, etc.).

  • Enhanced readability: Font sizes have been increased in Activities, Plans, and HR zones based on user feedback.

  • Better empty states: Activities and coach welcome views now provide clearer guidance when no data is available.
