Black Line to Buoy Line: Swim Clinic Series
About this race
Black Line to Buoy Line: A 4-Part Swim Clinic Series for Triathletes
Four Saturdays. Ten swimmers. One progression from pool mechanics to open water swimming for triathlon.
Most triathletes try to get faster in the water by swimming more. More yardage helps, but it also reinforces whatever you are already doing, good or bad. This series works in order: fix position first, add propulsion second, practice open water skills in the pool, then take it all outside.
Position ➡️ Propulsion ➡️ Pack ➡️ Plunge. We've got it covered.
Each clinic is 2 hours and builds on the one before it. As such, you should plan to attend all 4 sessions.
Clinic 1: Position, Saturday, February 27, 3:30-5:30 p.m., Green Mountain Rec Center, Lakewood, CO
Reducing drag is the cheapest speed you will find. We work on head to toe alignment, side to side balance, head and breathing position, and core engagement.
Clinic 2: Propulsion, Saturday, March 27, 3:30-5:30 p.m., Green Mountain Rec Center, Lakewood, CO
How the catch, pull, and kick produce forward speed, and where most of us lose it. Drills are mixed into swim sets so you feel the change while swimming, not only in isolation.
Clinic 3: Open Water Skills and Group Swimming, Saturday, April 24, 3:30-5:30 p.m., Green Mountain Rec Center, Lakewood, CO
Practiced in the pool, where it is easier to coach and repeat. Sighting, swimming close to other people, drafting, and buoy turns.
Clinic 4: Open Water, Saturday, May 22, 8-10 a.m. Chatfield Gravel Ponds, Littleton, CO
The skills from the first three clinics, tested in open water with the group and support on the water. In the event that the water is still too cold on May 22nd, May 29th will be the back up date for this session.
Why ten swimmers
These will be coached sessions. To ensure personalized feedback, we cap these clinics at 10. It also keeps open water safe and manageable for Clinic 4.
