Hey everyone,
If you’re using the Magic Buckets (XMB) feature for outdoor training, one handy trick is to use the XMB Generated Workouts tool (more info here) - not to follow a workout, but to help pre-plan your ride duration, route, and effort level before heading out.
Here’s a quick step-by-step guide on how I’ve been using this tool to plan some of my training:
Step-by-step:
-
Go to your Fitness Planner on Xert
-
Open the Magic Buckets tab from the Recommended Training modal:
- If you’re using XFAI: Click the ‘Magic Buckets’ button on the forecast placeholder
- If you’re using XATA: Click the “+” button on a day, then select the ‘Magic Buckets’ tab
- From there, you’ll be able to:
- Preview your training duration
- See the estimated difficulty rating
- Adjust the interval duration or max Challenge Level to see how it affects ride time and difficulty
Tip: If you’ve got a large Low XSS target (like on a “Polar” specificity day), lower CL intervals are fine - you’ll accumulate plenty of XSS during the recovery segments.
For Mixed or Pure specificity, you’ll often find that higher CLs are more efficient.
- Since I’ll be using the Magic Buckets data field on my Edge 840 (or Xert EBC app on Android/Karoo), I don’t need to save the workout — just previewing is enough!
Why it’s helpful
You’re not going to perfectly follow this workout. Instead, you’re using it to answer:
“How long should I ride, and how hard should I go?”
Example:
If my daily target is 169 | 12.6 | 2.4 XSS, the generated workout might tell me:
-
~2.5 hrs at CL 3
-
~2.25 hrs at CL 4+
So now I know:
-
I should aim to select a 2.25-hour route (~65km/40mi for me)
-
Most of my efforts should be around CL 4–5
-
From there, I can fill my targets using Magic Buckets in real-time (on Android/Karoo or Garmin CIQ)
Additional tips:
-
You can still ride freely - no need to perfectly follow a fixed interval structure
-
Want to push yourself? Spend more time at higher CLs and shorten the ride (or shoot for CL 10 to trigger a Breakthrough
) -
Want an easier day? Stay around CL 2–3 and extend your ride a bit
Hope this helps! Let me know if you’ve tried this or want help interpreting your Magic Buckets for a ride you’re planning!
