200m in 23m pool

Postby swat » Thu Jun 02, 2016 2:34 pm

Hi all. It's been a while since I've posted here, hope all is good.

I'm thinking of entering a local biathlon. The race info says the swim section is 200m, but the pool it's at is only 23m long (I think it's actually 75 feet = 22.86m). This may be a silly question, but where in the pool will the start and finish be? To swim exactly 200m is 8.75 lengths, so will the organisers move the start or finish away from the wall, or will we just swim 9 (or 8?) lengths and ignore the discrepancy? I've tried to find an answer online but haven't had any luck.

Isn't that a question for the organisers?

It is, but while I'm waiting for a reply from them I thought I'd see if anyone here knew the answer :-)

If they've any sense, it's going to be 9 lengths!

I did a 5km last year in a 50 yard pool (=45.72m). We swam 109 lengths*, which is actually about 17m short, but 110 lengths would've been 29m over.

*Well, we should've done, but I miscounted and did 111. :lol:

That must have been frustrating Mike!

How do you keep count over such a lot of lengths anyway? I've never raced before so it's never really mattered for me, but I find it really hard to keep track when I'm swimming.

Oh, and the answer from the Biathlon organisers is that we'll swim as though it was a 25m pool, it just means that points can't be used as qualifying for national competitions.

How do you keep count over such a lot of lengths anyway

Well I have a swimwatch that counts laps - the problem is, in this kind of event, you inevitably end up with a mid-lap stop/start every now and then (either crashing into another swimmer's feet or else crashing into a lane rope), and the watch sometimes interprets that as a lap-turn. I actually overestimated how many false turns the watch had added (obviously preferring to err on the side of caution). Once you get home and download the data from the watch, it's easy to see where the false turns are because the lap times are way out - the software lets you merge them back together.

Fortunately this was a charity fund-raiser rather than a race per se, so I wasn't overly concerned about the recorded time (more about whether I could actually go the distance!).

Better to undercount that overcount then!

I've got a watch (TomTom multisport) that is supposed to count lengths but I always find it adds quite a lot of extra ones on. Maybe my open turns aren't smooth enough and it thinks my arm flailing around is me doing some really short lengths :-) The distance swum always seems to be an underestimate as well, but I guess if I don't touch the wall with my watch hand it is going to be.

I use a Garmin Swim watch and the lap count is spot on.

When i still used open turns, there was some difficulty with the timing of the turn.
e.g. 2 lanes 50sec total, 25sec per lane would be shown as 23sec+27sec.

Now using only tumble turns, everything is fine.
