Hi Stuart, great question!
If you’ve analyzed your previous XCO MTB races with Xert, you can select one of those races as a placeholder on your calendar, ‘Pin’ it, and then adapt your forecast around the race. This way, Xert will arrange your training to ensure you’re in a fresh status (blue stars) when the race begins.
If you haven’t analyzed past races with Xert, you can manually set the Focus, Specificity, and XSS using the ‘Manual’ toggle when selecting training for the placeholder.
For detailed steps, check out this thread: How to Adjust Forecast Around Preferred Workout Activities.
Hope this helps!
Cheers!
Scott
