I am sure your coach has already suggested this but get some time in your wetsuit before your upcoming April race. Wetsuits are great but they can be restrictive in the shoulder etc.. I personally have a full sleeve suit and also a sleeveless suit and prefer the sleeveless when conditions allow it. Also, (again your coach probably has this schedule) see if you can practice an open water swim sometime before the race and start to work on sighting in the pool and during your open water practice. Sighting can change your stroke and rhythm up a bit and it is good to get those sensations before your actual race. Appreciate your dedication to your upcoming races. To me (and you have probably heard from many other triathletes) the "process" of getting fit is almost equal to the actual race.
Thank you for the informative comment. I usually get my workout schedule a week in advance but I’m sure my coach has something scheduled. I’ll mention it just in case. It sounds cheesy but it really is about the journey not the destination!
