24/7 electronic music streaming from around the globe
The provided GPX file records a walking activity in Zagreb, Croatia, starting near Ban Jelačić Square (a central landmark in the city) and ending at the lower station of the Sljeme cable car in Gračansko Dolje. This is a popular area, as the cable car provides access to Medvednica Mountain (Sljeme peak at 1,030 m), often used for hiking, skiing, or scenic rides. The lower station is at approximately 267 m elevation, which aligns closely with the GPX's end elevation of 278.9 m (minor discrepancies could be due to GPS accuracy or exact positioning).
Ban Jelačić Square, the central square of Zagreb, Croatia, is the city’s main meeting point and cultural hub. Named after Ban Josip Jelačić, a 19th-century Croatian governor and national hero, it features his equestrian statue, surrounded by historic buildings, shops, cafes, and trams linking all parts of the capital.

From City Heart to Mountain Start: Urban-to-Nature Challenge Trail
The track appears to follow a northward path from the urban center into the foothills, likely along city streets and paths. Normally, this journey is quicker by public transport (e.g., tram 14 from Ban Jelačić Square to Mihaljevac, then tram 15 for 4 stops/6 minutes to Gračansko Dolje, with the stop right next to the station), but your data indicates a full walking route instead.
Based on parsing the available track points (noting the truncation in the provided data, which omits much of the middle section but allows for key calculations and estimates):
Basic Activity Details
- Activity Type: Walking (as specified in the GPX).
- Name: Afternoon Walk (though the start time is morning—perhaps a misnomer or local time zone consideration).
- Start Point: Latitude 45.813298°N, Longitude 15.976541°E, Elevation 131.3 m (central Zagreb, Ban Jelačić Square).
- End Point: Latitude 45.860538°N, Longitude 15.982528°E, Elevation 278.9 m (Sljeme cable car lower station, Gračansko Dolje).
- Start Time: 2025-10-24T09:55:40Z (UTC, equivalent to ~11:55 AM local time in Zagreb, assuming CEST).
- End Time: 2025-10-24T11:10:10Z (UTC).
- Total Duration: 1 hour, 14 minutes, 30 seconds (4,470 seconds).
Distance and Speed
- Approximate Straight-Line Distance: 5.25 km (calculated via Haversine formula between start and end points).
- Estimated Path Distance: 5.5–6.5 km. This is based on the straight-line estimate plus typical urban walking route adjustments (e.g., following streets like possible paths via Ilica or northward avenues). The truncated middle section likely accounts for most of the route, but the visible points show gradual progress north-northeast with minor detours. Comparable city-to-foothills walks in Zagreb are around this length.
- Average Speed: ~4.5–5.2 km/h (total duration including pauses). This is a leisurely pace, typical for a relaxed urban-to-suburban walk with stops. Excluding pauses (evident from repeated points at the same location), moving speed may be closer to 5–6 km/h.
Elevation Profile
- Starting Elevation: 131.3 m.
- Ending Elevation: 278.9 m.
- Net Elevation Gain: +147.6 m.
- Estimated Total Elevation Gain: ~150–160 m (accounting for minor descents in the early points, e.g., a ~2 m drop from 131.3 m to 129.2 m, followed by steady climbs). The visible sections show gradual ascents (e.g., from ~129 m to 144 m in the beginning, and 271 m to 278 m at the end), suggesting a mostly uphill route with low-grade inclines suitable for casual walking. No major steep sections are apparent in the data.
- Elevation Loss: Minimal (~5–10 m total based on visible fluctuations).
- This net gain matches the transition from Zagreb's city center (~120–130 m) to the mountain base (~270 m).
Cadence and Pace Insights
- Cadence (cad): Values range from ~45–65 steps per minute (e.g., 55 at start, up to 65 in later points), averaging ~55–60. For walking, this indicates a slow, strolling pace (normal walking cadence is 100–120 steps/min; lower values suggest relaxed or cautious movement, possibly with sightseeing or rests).
- Pauses: Frequent stationary periods (e.g., multiple points at the same coordinates with advancing timestamps, like 2–4 seconds apart without movement). This suggests breaks for rest, photos, or navigation, totaling ~10–20 minutes of the duration. Examples include clusters at 45.813191°/15.978441° and 45.816535°/15.978272°.
Route Overview
- The path begins in the bustling center of Zagreb and heads generally north-northeast, transitioning from urban streets to more suburban/foothill areas. Visible early points show movement along or near major avenues (e.g., increasing longitude slightly eastward initially, then steady latitude increase northward).
- Potential landmarks en route (based on typical paths): Passing near the Cathedral of Zagreb (visible in early coordinates), through residential areas, and into the Gračani neighborhood before reaching Dolje.
- This route is an alternative to hiking the full mountain, which can be 10–20+ km with 900+ m gain to the summit. Your walk stops at the cable car base, where you could continue up via gondola (16–22 minute ride, ~5 km cable length, 763 m gain to summit).
Additional Observations
- GPS Data Quality: High resolution (points every 1–2 seconds), but with truncation in the provided file, full path analysis is limited. If the complete file is available, more precise distance/elevation could be computed.
- Conditions: Recorded on October 24, 2025 (autumn), likely mild weather for walking. The route is accessible year-round but could be slippery in rain or snow.
- Recommendations: Good for fitness, the pace was relaxed; for efficiency, public transport is faster (~20–30 minutes total).
A circadian rhythm is the body's 24-hour internal clock that regulates the sleep-wake cycle, influencing hormones, body temperature, and other biological functions. To gain and maintain a good circadian rhythm, establish a consistent sleep-wake schedule, even on weekends. Expose yourself to natural sunlight upon waking to signal daytime. Dim lights and avoid screens 1-2 hours before bed to promote melatonin production. Incorporate regular exercise, preferably in the morning or afternoon, and maintain a balanced diet with limited caffeine after noon. Avoid naps longer than 30 minutes. Consistency is key for aligning your body's internal clock with the 24-hour day.
