Swimming is my strongest Event
I have been swimming since 3 years old and competed in club and county level gala's for 100 fly from 5- 13 years old (family tragedy stopped me).
However it amazes me the precision and effort people put into their run and bike training but just do their best to survive in the pool/lake.
Appraoch Swim it the same way
Warm Up, main set, cool down
Endurance session
Anaerobic session
Drills session.
you can build up to the distance's you should already have aerobic endurance from your bike and your run you just need to convert to swimming as well. I know for a lot it is the fear of the water.
As well as doing Bike - Run brick sessions do swim - cycle ones every now and then.
I find it's more getting my breathing under control as i come out the water to the bike as i am going from long slow breaths to normal breathing again.
my run is weak i will cut one bike session over winter for a run, but i never cut swimming sessions as i think the the advantages you get in lung capacity from swimming is awesome.
