Nothing is changing for me. I have a set routine where I do 30 minutes of strength training in my basement before work every morning - rotating different muscle groups everyday. I plan to continue that routine. I run outside by myself so my running routine is also not changing.
For strength training I have a full set of weights, benches, dumbbells, and a full rack with pull downs and pull ups in my basement. That being said, you absolutely do not need weights to do strength training. And since I work out every day and mix it up, I often do workouts with no weights. You can Google videos. There are tons of great routines out there. Find ones that work best for you and don't forget to mix it up.
For races, I had planned to do one each month this Spring -- 5K in March, 10 Miler in April, a 10K in May and a Half in June. The 5K was today and of course it was canceled but I ran it virtually and did it in 20.14 which was 58 seconds faster than the guy who won my age group last year and 41 seconds faster than my last 5K six years ago. My 10 Miler in April will most likely be canceled and I am planning to do that virtually, too. I am hoping the 10K and Half will happen.
