What could you race?

I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Jones Beach could look like.

Your age and race category help me estimate where that performance could place you. They don’t determine how fast I think you can race.

Change units

The parkway makes speed visible. The boardwalk tests the cost.

The ride repeats its ramps, northern turnaround and Bay Parkway section before you change to running. Each boardwalk circuit returns towards transition, with the finish beside it after lap three. Use the first visit to each turn to learn the line, not to prove a split.

Zach’s Bay

Follow the bay loop without assuming calm water.

The Zach’s Bay swim runs counter-clockwise for one lap. Leave room to establish your stroke and sight the turn buoys. Do not confuse a sheltered setting with a guarantee of calm water.

Follow the counter-clockwise markers. Keep the opening breathing controlled.

Wantagh Parkway · first lap

Learn the ramps at an effort you can repeat.

The linked map takes you north on Wantagh Parkway, through the Old Country Road turnaround arrangement, then back via Bay Parkway. Come out of the aero position early for ramps and turns. Learn the lane instructions while holding your planned power between them.

Follow the signed lane changes. Brake before each turn.

Wantagh and Bay Parkways · second lap

Ride the second round with the boardwalk in mind.

The second lap repeats the route before the final return to transition. If wind changes the split, keep the power sustainable rather than trying to equal the first lap. Finish your planned fuelling where the road is clear, then prepare for the dismount.

Keep attention on the repeated ramps. Fuel before the final approach.

Ocean Parkway tunnel and boardwalk

Settle after the tunnel before looking at pace.

The latest map sends you under Ocean Parkway through the East Bathhouse West Tunnel and west along the boardwalk. Let effort settle after the tunnel. Around the West Bathhouse loop and other turns, shorten the stride and regain pace gradually.

Follow the current left-side running instruction. Do not chase pace through the turns.

Later boardwalk laps to IRONMAN Village

Count the returns before committing to the finish.

The October map repeats the boardwalk course for three laps, returning past transition each time. Treat those returns as checks on breathing and fuelling. After the final lap, follow the diversion into IRONMAN Village beside transition and use only the effort you can hold to the line.

Count completed laps deliberately. Check the final finish diversion.

What to check in race week

Read the current bike instructions for the Old Country Road lane change, ramps and turnarounds, including where temporary left-side riding applies. Walk the swim-to-rack route at Jones Beach Theatre. Check the tunnel, lap return and finish diversion on the latest run map, then review bay conditions, coastal wind and aid provision for your race.

Build the legs.
Practise the decisions.

A finish range gives you something to work towards. The preparation is specific to this race: I would work on holding your riding position comfortably while keeping enough attention for ramps and course instructions. Rehearse a run with repeated turnarounds after the bike. We can use those sessions to choose an effort you can maintain when the parkway feels fast and the boardwalk pace starts to fluctuate.

I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Jones Beach.
