When is the Paris 20K 2027 and how do you register?

The Paris 20K 2027 will be run on Sunday, October 10, 2027: the official website says "see you on October 10, 2027". The race is organized by the Club des 20 km de Paris association, under the aegis of the City of Paris; the 2026 edition, the 48th, had 35,000 registered runners according to the organizer. It is a 20 km (12.4-mile) road race on a single loop, with a World Athletics Road Race Label and the French federation's FFA International label.

Bibs are sold in price tiers and the race sells out: for 2026, online registration went through the Njuko platform, with no refunds and no bib transfers outside a possible official resale platform. Individual prices for 2026, as published in the rules:

• — First 2,000 bibs: €55; next 3,000: €59; next 5,000: €65; then €71 until sold out.
• — DUO (team of 2) and TEAM 4 (team of 4) offers: €3 to €5 less per bib depending on the tier.
• — Para athletes and joëlette (all-terrain wheelchair) team runners: €40; groups (companies, clubs, associations): specific prices via groupes@20kmparis.com.

The course: a 12.4-mile loop through western Paris

The Paris 20K course starts on the Pont d'Iéna at 9 a.m. and returns to the foot of the Eiffel Tower after a loop through the Bois de Boulogne, past Roland-Garros and along the Seine. The organizer describes it as fast, with few changes of rhythm, and announces finishing times from 58 minutes to 2:50. The main stages of the 2026 edition:

In 2026, aid stations were at miles 1.9, 3.7, 6.2, 7.5, 9.3 and 11.2 (km 3, 6, 10, 12, 15 and 18), plus the finish (water, fruit, sugar). Under the rules, each runner has 2 hours 50 minutes from their own start to complete the 12.4 miles, an average pace of 13:41 min/mi; a chip records splits every 5 km (3.1 miles), and every split must be recorded to be ranked.

Start waves, pacers and bib pickup

The Paris 20K starts in 60 waves of 500 runners, one every 2 minutes, to avoid congestion in the first miles. Pacers run with a flag showing their target finishing time: the organizer advises lining up close to the one that matches your goal and keeping them in sight.

Bibs are collected at the race village with an ID and the pickup voucher emailed one week before: in 2026, the village was open on the Friday and Saturday before the race, and no bibs were handed out on Sunday. For runners who cannot come to Paris, the organizer also offers a connected (virtual) version of the race, with its own rules.

Training for the Paris 20K in 10 weeks with Running Workout

The Running Workout half marathon plan suits the Paris 20K: it lasts 10 weeks, with 3 or 4 sessions a week, and assumes you have already run at least 60 minutes non-stop in the last three months. For a race on October 10, 2027, it starts in early August. Each session is sent to your watch through Garmin Connect, with paces worked out from your MAS (maximal aerobic speed).

Ask your connected assistant (Claude, ChatGPT or Gemini) for one adjustment: the plan's race-day workout is written for a half marathon. Ask for a 12.4-mile workout at your goal pace, with a cautious start in your wave. The assistant builds it and sends it to your Garmin watch; it can also shift the plan if the 2027 date changes.
