Have a number of things that might help taking attention off your stressors, such as load some music on your phone and have headphones, book, tablet with movies etc Depends what keeps you distracted.

Make a list of what could be helpful when you are overwhelmed. Prepare to post in PC or journal etc Think of people you can text or call if you need it.

depends on what works for you normally.

PS going from bike ride to a concert might be too much. Make your ride short. Like 30 minutes. So you have more time in between
