Help me break through a wall please!

These are short course 25 meter races. The pools here in Hokkaido are all quite old, and I haven't come across any blocks where I could feasibly do a track start. All the blocks are tiny, and some are not even angled forward. I used to swim 50km a week in school, but quit when I was 20. Now I'm 28 and have just gotten back into swimming. Work keeps me pretty busy, so I only swim once a week. Just about 1.5 km. It's just for fun. I don't race 100's or 200's because I just don't have the fitness. 25's and 50's I can get away with anaerobic, so I don't really need to be too fit! What's a jammer? Is that a fast suit? I'm from an era before those! I like my Alexandre Popov style costume! This weekend I'm swimming a 25 and 50 free, and a 50 fly down in Obihiro. It's SC. I'll really work my SDK and try and keep my head down. Fingers crossed I can get a 23.
