How to Turn a Strava Activity into an Instagram Reel in 60 Seconds

*Stop posting flat GPS screenshots. Here is how to create eye-catching 3D video reels from your Strava workouts.*

The Problem with Static Map Screenshots

When you finish an epic marathon, mountain bike descent, or alpine summit hike, sharing a flat orange-line map screenshot on your Instagram Story rarely communicates the true magnitude of your effort. Flat maps hide elevation vert, dramatic ridges, and route complexity.

By transforming your workout into a vertical 9:16 3D animated flyover, viewers can experience the scale, terrain, and speed of your adventure.

Step-by-Step: From Strava to Instagram Reel

1. Grab Your Activity GPX

On Strava.com, click the ••• Actions menu on your activity and click Export GPX.
Or use the TrailShorts Chrome Extension for 1-click import.

2. Configure for Instagram (9:16 Vertical)

Head to Trailshorts.xyz and upload your GPX file.
The 3D generator automatically presets your aspect ratio to 9:16 Vertical (1080x1920) — the exact resolution required by Instagram Reels, TikTok, and YouTube Shorts.

3. Customize the Visual Aesthetics

Pro Tips for Maximum Engagement on Instagram

Add Trending Audio: When uploading the MP4 to Instagram Reels, pair it with trending ambient or upbeat electronic music.

Combine with Photos: Use Instagram's editor to split the Reel: start with your 3D route flyover, then cut to your on-trail action photos.

Include Key Stats in Caption: Highlight total elevation gain, moving time, and weather conditions in your caption.
