Riverside Park at 101st St
Entrance to the park – Riverside Drive & 97th St

The NYC Triathlon will have one Transition Area at Riverside Park on the soccer fields at 101st St. where athlete bikes/equipment will live.

To mitigate crowding on race morning at Transition and at the Swim Start, athletes will be assigned to five different groups: Red, Yellow, Gold, Green and Gray, which exist to designate pre-race access to the Transition Area and the Swim Start areas on Sunday morning (see below).

Important Notables
Only athletes wearing their race-issued wristband will be permitted to enter the Transition area. Bike stickers must be affixed prior to entering Transition for bike check-in (Saturday only).

Gear brought into Transition must be placed inside clear bags received at Packet Pickup – no backpacks or duffle bags! Athletes may empty all items into the clear plastic bags, then once in Transition may place those items into an empty backpack or duffle bag. Items must be placed directly underneath each athlete’s racked bike.

Athletes will rack their bike in a specifically assigned area within Transition, designated by the color of the assigned athlete wristband and race number. Athletes will find the rack that corresponds with their race number and rack their bike by the seat or handlebars at their specific number.

Security will be onsite overnight. Bikes are not allowed to be covered – any covers left overnight will be removed by race management. Athletes are encouraged to bring a towel race morning to wipe down their bike (access times listed below).
