Missed 2 hours Tuesday, and probably 3 hours today, I've been struggling as I can't go outside on days like today when it ****ing snowing in mid march

! and its hard to do it inside, im just soo busy with crap. I have 2 hours tomorrow but could possibly turn that into 3. All rides are just endurance paced.
How do you guys handle missing training like this? It's not just one ride. But will missing these few rides of 2-3 hours of endurance hurt me a lot? I have my first race in 13 days and have trained my butt off like crazy for it, I have seen great improvements as of 2 weeks ago, but will missing these rides have a significant impact on me?
