Discount entry deadline Monday night
On Saturday, there's the chance to ride the route the stars of British cycling will be using for the national road championships the following day.
The Canaccord Genuity Sportive takes in a lap of the TT course, with around 270 amateur cyclists signed up so far.
The Mountain Road section, from Barrule Park to the Creg-ny-Baa will be closed for the event, giving those taking part the chance to ride the iconic section without the worry of traffic speeding past them.
You can turn up and take part on the day, but Monday night is the last chance to enter at the discounted rate, as Alex Toohey of Canaccord (who himself is doing the sportive) explains:
