The Paris Half Marathon is only a few weeks away! If you still haven't started your preparation, all is not lost, because the organizers have set up a training program to help you.

If you've never taken part in a marathon or a race that requires a bit of training, don't worry, the organizers of the Paris Half Marathon have put together a training program to get you ready in time. With just a few weeks to go before the event, you need to be seriously prepared to run just over 21 kilometers! In addition to these programs, nutritional plans and advice on mental preparation are also offered. So, shall we get started?

On the official Semi app, you'll find challenges designed to keep you motivated — and offered with prizes! The "Objectif Semi" podcast provides tips to help you prepare, whether it's mental strategies or physical training.

Depending on your target time, the website offers various training plans along with a comprehensive training guide, especially helpful if it's your first marathon! For those interested, training sessions are also organized in collaboration with the French Athletics Federation.

In the weeks leading up to the marathon, steer clear of greasy foods, alcohol, and anything that might upset your digestion. Getting plenty of quality sleep is crucial for building up your energy reserves and performing at your best on race day.

On the big day, the 21 kilometers will be challenging to complete, but the key is to stay committed and be proud of yourself. Push yourself to the limit without risking injury! The toughest part will be the final kilometers, so conserve your strength throughout to finish strong. And don’t overlook the importance of refueling during the race!

Until race day, limit yourself to three running sessions a week, each lasting about an hour, to avoid overtraining. Incorporate interval training to boost your cardiovascular endurance.

Adding strength training and core work can only help! Prepare comfortable gear and don’t worry—you’re fully capable of completing this race if you run regularly. After that, you can start thinking about preparing for the Paris Marathon, which is a bit more demanding!
