Every December, Strava publishes the Year in Sport - a global report of aggregate stats from millions of athletes. Every athlete also gets a personal "Year in Sport" recap video, showing their stats over upbeat music. It's wildly popular. People share it on Instagram. It's a marketing coup.
Baseline's annual review (shipping later in 2026) takes a different approach. This post explains the philosophy, what we're building, and why "analytics" and "recap" aren't the same thing.
What Strava's Year in Sport is
Strava's recap is:
- A 60-second video montage of your stats
- Set to music
- Showing your total distance, time, elevation, top sport, fastest effort
- Designed to be shared on social media
It's well-produced. It's fun. It's free. And it's almost entirely a marketing product - designed to get people sharing the Strava brand during December.
There's nothing wrong with that. But it's not an analysis.
What Strava's recap doesn't do
- Compare your year to previous years
- Show your training load progression (CTL build, peaks, tapers)
- Surface which training blocks produced results
- Cross-reference your performance with recovery/sleep data
- Identify actual performance breakthroughs vs steady accumulation
- Give you a PDF you can send to your coach
It's a highlight reel. Fun for five minutes. Forgotten by January 2nd.
What Baseline's annual review will do
1. Year-over-year comparison
Your 2026 stats laid against 2025. Not just total distance - did you get faster? Did your CTL peak higher? Did your workouts get more structured? The trends are more interesting than the totals.
2. Training block analysis
The annual review automatically detects your training cycles from the data: base periods, build blocks, peak/taper, recovery weeks. It shows you which approach produced results and which didn't.
If you ran a marathon in April and improved your 5K PB in October, the review shows you the CTL ramp that led to each - and how they differed.
3. Performance breakthroughs
Not just "you got faster" - the review identifies specific moments when your fitness meaningfully changed. The workout that broke a plateau. The recovery week that unlocked a PR. The training block that didn't work.
4. Cross-source correlations
If you wear a WHOOP and a Garmin, the review shows you how your recovery metrics correlated with your training. Did higher HRV weeks precede better performance? Did poor sleep consistently undermine your training? These patterns become visible across a full year of data.
5. Geographic year
Every location you trained in, on one map. Countries, states, cities. Total elevation gained. Highest altitude reached. Furthest south you've trained. A genuine travelogue of your training year.
6. Shareable, beautiful, yours
A web page you can share (if you want), a PDF you can download, and an OG card for social media. But the content is analytical depth, not a marketing montage.
The pitfalls of relying on a single-source year-end review
If you train across multiple devices and platforms - a Garmin watch for runs, a Wahoo head unit for rides, Apple Health for sleep, and WHOOP for recovery - no single endpoint has the full picture. Your Garmin knows your running volume but nothing about your WHOOP recovery trends. Strava sees your uploads but cannot tell you whether those workouts happened in a week of 95% or 45% recovery. A year-in-review that pulls from only one source is like reading every third page of your training diary and calling it complete.
The most common distortion concerns training load. If you log many of your rides on a head unit that syncs directly to TrainingPeaks rather than through Strava, your Strava year-in-review undercounts your cycling by hundreds of kilometres. Your cycling, when properly accounted for, might represent 40% of your annual training load instead of the 20% Strava reports. In a multi-sport year of marathon training plus cycling cross-training, the error compounds: marathon volume looks disproportionately high relative to cycling simply because the data sources differ. The narrative you take away is wrong and the training lessons you draw from it are misinformed.
A second distortion: recovery context is entirely absent from most year-end summaries. You might see that April was your highest-volume month, but you cannot see that your recovery was also at its worst - that 90% of your sessions were performed with suboptimal HRV and poor sleep. The volume number reads as an achievement. The recovery context reads it as a warning. Without both, you risk celebrating the month that actually set you back physically.
What Baseline does differently: the year-in-sport pulls from every connected source, normalises the data, and layers it onto a unified timeline with recovery metrics, sleep quality, and injury/pain flags. The output is not "here is your biggest month" but "here is the month where your training was most productive, and here is why."
Why we're building it
I built Baseline because I wanted to see my own data. The annual review is the logical extension - the report I always wanted at the end of each year but never got.
Strava's Year in Sport is fun. Baseline's annual review will be useful. Both have their place. One gets shared in December. The other gets read in January when you're planning your next season.
When
The annual review ships in the second half of 2026, in time for the December reflection season. It'll be available to Pro and Founder users.
If you have a full year of training data by then - 2026 is the year to start keeping it in one place.
Common mistakes
1. Treating a year-end recap as meaningful analysis. Strava's Year in Sport and similar annual recaps are designed for sharing, not for understanding. Total distance, time, and elevation make for a fun social post but tell you almost nothing about whether your training actually worked. Real analysis requires year-over-year comparison, training block breakdown, and performance context. A highlight reel is entertaining, but it will not help you plan next season.
2. Comparing your year to others without context. Seeing a friend's 12,000km year can feel discouraging if you only managed 6,000km - but that comparison ignores lifestyle, family commitments, work stress, training history, and what each of you was actually trying to achieve. The only meaningful comparison is against your own previous years, with context about what changed in your approach. Did your CTL increase? Did your training become more structured? Those are the numbers that matter.
3. Looking backward without planning forward. A year-end review is most valuable when it informs next season's plan. Many athletes consume their recap passively, enjoy the nostalgia, and move on without extracting any actionable lessons. A proper annual review should answer three questions: what worked this year, what did not, and what will I do differently next season? Without that final step, you are just collecting memories instead of building a better training plan.
How Baseline handles this
Baseline's annual review is built for analysis, not marketing. It shows year-over-year comparisons of key metrics, detects training blocks automatically from your data, identifies performance breakthroughs, and correlates recovery metrics with training outcomes. It produces a downloadable PDF you can send to your coach and a web page you can share if you want - but the substance is analytical depth, not a marketing montage.
