On 5/21, I swam 8,000 yds in the pool in 2:31, i.e. 1:53/100 yds - non-wetsuit, non-tapered, the day after an Oly tri.
On 5/25, I swam 2 miles OWS - w/ wetsuit, a bit of wind, some chop in 1:08, i.e. 1:57/100 yds.
On 5/28, I swam back to back 1 mile and 2 mile OWS in a lake - w/ wetsuit, zero wind, zero current, zero waves, average 1:44 and 1:46/100 yds, respectively.
At GCBS, I swam 3:06, which I believe is 2:10/100 yds - w/ wetsuit, zero current at the beginning,
If I translate the 5/25 swim to 3:06, I should have swam about 5.5 miles --
I think if the currents had been much stronger, I would not have made the time cut-off.
Yesterday was my 17th finish, and I had four athletes there as well.
First, congratulations - it wasn't easy, it's never easy matter of fact.
There things you need to know about open water in general and the Bay Swim in particular.
General:
1. Unless you are swimming quite close to a fixed object it is pretty much impossible to determine if there is current and where it is going. In the same way that you have no sense that the earth is rotating around the sun and we are hurtling through space at mind-blowing speed, you have no sense that the entire bay or ocean you are swimming in is moving northward at 1 mph.You don't experience it much in triathlon, but in open water swimming it happens more often. My personal most extreme example is floating on my back having some discomfort in a swim in New York Harbor and the garmin shows we were doing 30 minute miles. But out in the middle there is no sense of that at all.
There are a few unique things about the Bay Swim:
1. Chuck the race director says some things to please the crowd. this year he did get the direction of the current correct, but his comment about the current being low was incorrect. The full moon was Friday, so we were swimming in a spring tide. The tidal index, which is the %ile of how big the swings in tide height are for a given location was 91 or 92 yesterday. The current was quite strong.
I know in my own case when we were near the main shipping channel, I had to turn to the right quite a bit to stay in the middle. I was also trying to draft off of someone, and it was like drafting in a cross wind on the bike, had to stay off to the side.
2. The curve of the bay bridge is much bigger than it seems when you are in it. Once you are in between the spans, you still have to swim to the south (upstream in this case) for quite a ways. Then, once you are in the straightaway, you still need to maintain yourself inside the spans. This is a unique challenge, in most tidal swims you just time it so that the tide pushes or pulls you wherever and you keep swimming across the tide. Not so at the Bay Swim since you have to stay in that relatively small spot.
3. The Bay Swim also presents a nutritional challenge. Most folks forget to pack something to eat after you take the bus over. But at over 2 hours long, you really do need something to eat and probably some calories during the swim as well.
All in all, I am not all that surprised by your time.
