ITB - illio- tibia band (sp?) the hard band that runs from your hip through your glute hamstring and quad to your knee. Every time i run it spasms and pulls my knee and hip out of alignment - bit sore:-(
For swimming go along to a tri-club swimming session or a masters session, the tri ones are usually better though as they should have a coach who is prepared to teach first principles rather than make you swim hard/fast.
Am swimming at 1.18-1.20 ish at the moment in the pool (fast at tumble turns so a bit slower open water more like 21-22 minutes for 1500) - should come back a bit faster as didn't swim other than races for 3 months (kept "forgetting" to go).
I found doing the weeks about i could do lsd, hard, hills etc whereas when i tried to do both disciplines i seemed to end up doing loads of recovery rides/runs. Every 3 weeks would be fine too
