IRONMAN 70.3 Muskoka.
Your best day in Huntsville.
Muskoka is made for triathlon: lakes, forest roads and a run back into Huntsville. It is also a race where the bike can make an eager athlete pay, especially if every rise becomes a chance to surge. Start with the right lake, then save something for the run.
Huntsville, Lake Vernon.

Your day in Huntsville
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 Huntsville could look like.
The course behind your race
The Lake of Bays ride should leave you ready for Huntsville.
Earlier courses took riders around Lake of Bays through Dwight, Dorset and Baysville before finishing on foot in Huntsville. That is a demanding enough day without borrowing somebody else's swim venue. Fairy Lake and Peninsula Lake both appear in current material; the 2027 start needs to be settled before you travel.
Dwight direction, previous bike circuit
Keep the early bike effort below the cost of climbing
Muskoka's hilly terrain rewards steady effort over racing each rise.
Cap opening effort. Fuel early.
Dorset and Baysville, previous cycling corridor
Fuel steadily through the lake-country roads
Finish planned nutrition and hold effort through the remaining hills.
Stay patient. Finish planned nutrition.
Downtown Huntsville, provisional run start
Let the first streets restore your stride
Let the wooded trail opening feel easy, not fast.
Easy first aid station. Check posture.
Huntsville run finish, precise route pending
Use the town atmosphere only when it helps
Only progress once the first half has held together.
Stay tall. Choose the last move late.
What to check in race week
Confirm whether the 2027 swim is at Fairy Lake or Peninsula Lake; available descriptions conflict. Once the venue is settled, check the Lake of Bays bike loop, Huntsville run, transitions, access and aid. Don't use an older map to decide where to park or rack the bike.

Your plan, in race week
Prepare for Huntsville
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: the correct lake start is known, riding around Lake of Bays stays within sustainable power and the town half marathon begins calmly.
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 Huntsville.
