Getting sick during a training block

An ounce of prevention is worth a pound of cure.

Get plenty of sleep. Take a multi-vitamin. Eat well and minimize junk food. Stay away from sick people. Wash your hands regularly and thoroughly.

take a few days off and allow your body to fight the infection and recover. if you power through it you'll just tire yourself out and chance for real injury increases. it's worth it to take a few days off to ensure you actually are able to jump back into your training plan on target, rather than keep struggling to catch up because you've not allowed yourself to recover

I go by what my body tells me. I don't mess with training if I'm overly fatigued while at rest or my body is otherwise showing signs of significant stress (increased resting heartrate, etc.). When training with an illness I will monitor heartrate during the workout to ensure I'm not overstressing my body. As I get better I tend to focus more on perceived effort and run based on what my body is telling me.

Sometimes my body surprises me and responds well to exercise when sick and I end up feeling much better after completing a planned workout. In other instances my heartrate will skyrocket and the feeling of fatigue will be overwhelming after a few steps and I have to call it a day.

Just got a light cold after months of good training and 2 months out from a 10k. When you already are fit it’s just about making sure you won’t be forced to take any major time off, so I’m taking a couple days of rest and then I’ll be back in shape in a week.
