The annual running festival at Westfield Parly 2 offers something for runners of all ages and abilities. The day kicks off with a relaxed 10 km scenic walk starting at 9:00 AM, designed to accommodate families and casual enthusiasts without the pressure of competition or timing. For younger participants, there's a fun-filled 1-kilometer run beginning at 9:15 AM for children born between 2016 and 2020. This short race is an ideal introduction to running events in a friendly and supportive environment. The main event starts with the competitive 10 km race, open only to those aged 11 or older, kicking off at 9:40 AM. The course winds through picturesque landscapes around Westfield Parly 2, providing runners with stunning views along the way. A separate category for marche nordique enthusiasts begins shortly after at 9:50 AM. Aimed at a slightly older age group is the 3 km race starting at 10:00 AM, open to those born in or before 2015. This event allows young runners and their families to participate in an energetic morning run amidst supportive cheers from spectators. Registration fees vary depending on the distance; for instance, the 1-kilometer dash costs €3 while entry into the 3 km race is priced at €5. The longer distances such as the competitive 10 km and marche nordique events each cost €15 per person or a discounted rate of €10 if registering in groups of ten people or more. Participants are encouraged to pre-register online before the event, though no on-site sign-ups will be available this year. Dossiers can be collected at INTERSPORT's shop located within Westfield Parly 2 in Le Chesnay-Rocquencourt between October 3 and October 7 from 10:00 AM to 5:00 PM, provided all necessary documentation is submitted ahead of time. A hydration station will ensure runners staying hydrated on the longer courses; water stops are available before the seventh kilometer for those taking part in the 10 km race. Upon crossing the finish line at any distance, participants can look forward to receiving a commemorative t-shirt and medal as well as some refreshments. For the competitive 10 km event, podium spots will be awarded across various age categories, recognizing individual achievements among adult competitors. The shorter races also feature their own accolades with awards given for top finishers in U14/Benjamins and U16/Minimes divisions during the 3-kilometer race. This family-friendly running festival is a celebration of movement and community spirit, inviting runners to enjoy the outdoors while supporting local athletes.
