There’s a lot you can do to stay active during a city travel. I’ll write about my favourites, which I always use whilst travelling;
Swimmming: Bring swimwear and go swimming somewhere local! It dosen’t even have to be in a swimming hall. The things to pack with you (swimwear, bathing cap, towel and goggles) are light to carry, and if you think smart they don’t take much space.
Jogging: Jogging can be done almost everywhere, and all you need is jogging shoes and some comfy clothes!
Hotel jam: Many hotels has got a mini-jam open for the visitors. If this is an opportunity where you’re staying, you can E.G coordinate it with jogging outside. You need comfy clothes and good shoes!
Hiking: Cities surrounded with mountains has mostly got good hiking opportunities. Search them up and get a map!
