IRONMAN 70.3 Bolton.
Race Bolton on your terms.
Bolton's half-distance course doesn't fit neatly into one venue. Pennington Flash lies away from the town-centre finish, and the ride through the surrounding roads asks for more restraint than a simple 'fast' bike label suggests.

Your day in Bolton
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 Bolton could look like.
The course behind your race
The road from Pennington Flash ends with a real half marathon.
The earlier Bolton course starts at Pennington Flash, heads onto roads including Chorley New Road and brings you back through Queen's Park towards the Town Hall. You need both climbing restraint and a good travel plan here. The 2027 map still needs confirmation, so don't build your morning around last year's closure list.
Bolton area bike, opening roads
Set sustainable power before climbing
The early village loops are where you make the later climb manageable.
Cap opening effort. Fuel early.
Chorley New Road, previous route
Let changing gradients alter speed rather than power
Use Victoria Road and Old Kiln Road without forcing the effort above plan.
Shift early. Recover after the climb.
Queen's Park, previous run setting
Allow the opening town kilometres to settle
Use the first loop to recover from the bike before deciding pace.
Control the first aid station. Keep the first loop easy.
Bolton Town Hall, prior finish approach
Use the last effort only once you've earned it
Only race the return through central Bolton when form has held.
Check posture. Choose the last move late.
What to check in race week
Confirm the 2027 date, Pennington Flash swim, bike route and Queen's Park run before organising transport between lake and town. Road closures, transition access and aid can change between editions. Don't use 2026 closure times as a race-morning itinerary.

Prepare for Bolton
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: the athlete can handle dispersed race logistics, controlled climbing and a town run without letting the excitement of the finish pull effort forward.
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 Bolton.
