First, I wouldn't stress out too much about it. Most masters groups have a pretty wide range of ages, body types, and abilities. Most people in my group
(that I swim with in the summer
) are middle aged or better, most have kids and jobs, many are slow, and probably a lot of them eat too many nachos sometimes! We all have our vices. That being said, tips I can think of might include:
*Let the coach know your concerns. Ask him/her what's the best lane for you to swim in, and don't be afraid to ask any questions to clarify the workout.
(Other swimmers are usually glad to explain as well.
)
*I would wait on equipment until you know what is available at practice. At most of the pools and masters clubs I've swum at, pull buoys, kickboards, and sometimes fins are available, though a few people have their own. In my club, more people bring their own paddles as people prefer different sizes.
*When you can, learn flip turns. It really helps the workout go more smoothly if most other people in your lane do them.
(I'm a fairly fast swimmer but occasionally in cold water my back cramps and I just physically can't do them; a few years ago I bruised some ribs in an accident and couldn't flip for two or three weeks. It drove everyone nuts--I'd be going at a god pace, then slow down at every wall!
)
*Someone tapping your feet means they want to pass. Let them go by
(if they can without crashing
) beside you, or let them go in front on the next repeat.
*For the more pure-swimmer type clubs
(you'll know!
), wearing a wetsuit to practice, or mentioning triathlon, might give rise to some ribbing. I sometimes wear my mini-wetsuit when the water's cold due to the aforementioned cramping, and had people griping about "triathletes who can't swim without wetsuits" and
(after I beat some of the gripers
) "unfair buoyancy advantage". They
(mostly older guys with big egos
) finally shut up when I completed the club's "800m IM challenge", sans wetsuit.
