I am participating in a 5km-runing relay event organized by my employer. One of my colleagues dropped out, and couldnt find replacement. Now I offered to run also his 5k.
Running 10k is no problem for me, since I have done that already a couple of times (just below 45 minutes). Normally, in a race you are running the 10k in one go, but due to the nature of the relay race, a colleague suggested that I could take a break of about an hour in between(in which my other teammates run their 5km).
I am in doubt whether taking a break in between is a good idea. On the one hand you can get some rest and refuel for the second 5km, but on the other hand your body will switch to recovery mode during the break.
I am just wondering if there are any studies or experiences that could inform me on this decision? Or any tips for how I should use the break in between?
