The beginning of this year brought significant changes to the run energy mechanics in Old School RuneScape (OSRS), making agility training more rewarding than ever. With faster energy regeneration, particularly at lower levels, and a system where your agility level influences energy drain alongside your weight, now is the perfect time to prioritize agility training. Let’s break down how to take full advantage of this update, optimize your training, and level up your agility effectively on OSRS gold. 

Why Train Agility?
Simply put: to run longer. This essential skill has numerous benefits in OSRS, including unlocking important quests like Song of the Elves, which requires a level of 70. Additionally, agility training can enhance your efficiency in various activities throughout the game. With the new energy mechanics, getting started on agility sooner rather than later will allow you to reap these benefits quickly.

Utilize Summer Pies
One of the most valuable items for agility training is the Summer Pie. This pie not only heals but also boosts your agility level by five. This temporary boost can significantly increase your XP per hour, as you’ll be less likely to fail obstacles and can even gain access to higher-level courses earlier.

Optimizing Your Weight
Energy drain is now influenced by both your agility level and your weight. To minimize energy loss while running courses, keep your weight at zero. Equip lightweight items such as:

Graceful Outfit Pieces: Available for exchange at the agility shop in the Berto pub using Marks of Grace.
Other lightweight gear to help you remain agile and preserve your run energy.
Agility Courses Overview
Levels 1-20
Start your agility journey at the Draanor Rooftop Course. You can access this right after Tutorial Island, which will take approximately 30 minutes to reach level 20. Alternatively, complete the Tourist Trap Quest to gain agility XP and skip directly to level 26.

Level 20: Brim Haven Arena
The Brim Haven Arena is an excellent spot for agility training starting from level 20. Here, you'll chase ticket dispensers that award you agility tickets and experience that scales with your level.

Level 52: Wilderness Agility Course
At level 52, head to the Wilderness Agility Course for better experience, provided you can dodge the dangers of PvP combat. Utilize the ticket dispenser here for experience tickets, which you can cash in for more XP with a streak bonus.

Complete the Candin Heart Diary for bonus XP and easier transportation to the Sears Village Rooftop Course, enhancing your XP rates significantly.

Level 70 and Beyond
Unlock the Paw of Niche Rooftop Course at level 70, which also benefits from completing the hard Desert Diaries. If you’ve completed Song of the Elves, switch to the Pri'tennis Course for crystal shards and unique training experiences.

Level 90: Ardougne Rooftop Course
When you hit level 90, the Ardougne Rooftop Course becomes your go-to for maximum XP, especially if you’ve been collecting Marks of Grace along the way.

AFK and Chill Training Options

Colossal Worm Course: Low-effort with animations that allow for good AFK opportunities.
Penguin Course: A fun way to also work on your pet collection while leveling agility.
