Hey Tommy,
Thanks for reaching out to us!
The highest level class that we have on that template is “.tribe-events-pg-template” so you can try targeting that class within your CSS file and making it wider. However, depending on your template, there could be an additional wrapper that could be causing the current size issue on that template. Without being able to see the live site (currently a lander modal on the site) it’s hard to say exactly what the solution would be here.
Thanks!
