Swim cords/tethers for hotel pools
First time poster and TI beginner. I started my TI instruction as part of a triathlon class, and was the first time I have ever tried to swim (I'm 45). Now that the triathlon is done, I want to continue to build on my progress. The problem is that I often travel for work and can only access hotel pools. I can work on drills in the pool, but would like to start to expand the drills to work on my breathing. Has anyone used swim cords/tethers in hotel pools, and if so, are there any manufacturers you recommend? Thanks in advance for any help.
