ATTQOTD (Previous): Do you take a break from running following a race/race weekend? If so, how long? Do you also take a break from other workouts?
It depends on a variety of factors. But I ascribe to the Daniels methodology of one day off/easy for every 3km of racing. So a 5k requires 1.5 days, 10k 3 days, HM 7 days, and M 14 days. That's assuming the race was an "A" effort. If it's less than an "A" effort then I adjust expectations accordingly. If it was an "A" effort but the pace bombed at the end, then I'll consider extending the necessary recovery time since the pace bomb suggests some significant damage occurred.
It's important to recognize the other side of this in two-fold:
One is that the recovery is necessarily not only from the physical standpoint, but also from a training management standpoint. You can't be at your best all the time. It's necessary on a cyclical basis within the year to have periods of low and high. This allows you to reach optimal levels of training late in the training cycle yielding better racing results. When we stack too many training plans consecutively without appropriate down periods between, then we don't differentiate the training enough over the long term leading to stagnation of gains. Simply said, the lows allow the highs to be beneficial and not feel like you're grinding your gears. I wrote a post years ago illustrating this mathematically using the concept of training load.

The second is the despite taking 7-14 days off, it might feel like you've lost a ton of fitness in that time period. You haven't. At least not from the standpoint that it won't be easy to get it back. In my experience working with my own data, it takes about 28-42 days to recover from a hard marathon effort. So I'll restart hard training after about 4-6 weeks, with usually 1-2 weeks of no running, and then 1-2 weeks of only easy running (of equal time to the time off), and then based on the timing of the next "A" event, I'd start hard training again. And ideally the hard training would be aimed towards a different distance goal than the training plan I'd just completed to make sure I'm touching all areas of the pace spectrum over the course of the year.
