There are realistic expectations and wishful thinking one can be achieved initially, while the other needs time to materialize over time. Both require hard work and dedication. So here is a very generic training for a Half Marathon in 2:00 from my Speed and Strength Guide. To better match your fitness goals, I would have to see your daily data. There is no one-size-fits-all because it works for someone doesn't mean it works for you.
To run a half marathon (21K) in 2:00, you'll need to achieve a pace of approximately 9:09 minutes per mile. Given your current 10-minute pace for 10 miles, we'll focus on building your endurance and speed.
Speed Work: Interval Training
Let's start with Interval Training: what's interval training you ask? It's merely, alternate between high-intensity running and active recovery. For example:
- Warm up with 5-10 minutes of easy jogging
- 4-6 x 800 meters at 8:30-9:00 minutes per mile pace with 400 meters active recovery
- Cool down with 5-10 minutes of stretching
As we have been working out in the track all year progressively increasing the repeats and variations of distance of bouts.
Note: you must religiously do this weekly to avoid injury and assure success.
Tempo Runs
Our second variation is Tempo Runs: Run at a sustained, challenging pace for 3-6 miles to improve your lactate threshold. The key here is a challenging pace of nonstop running. When you stop before the distance it has no value as a tempo run.
Key: Tempo runs are designed to push you to a challenging pace, helping your body adapt to running at a faster pace. Stopping too early means you won't get the full benefit of the workout.
Long Interval Training
Incorporate longer intervals (2-4 miles) at a slightly slower pace than your goal pace.
The Purpose of Long Interval Runs
Long interval runs are an essential component of speed training, helping you build endurance, speed, and mental toughness. The goal is to run at a challenging pace for an extended period, typically longer than your typical tempo run or interval session.
What is Considered Long?
Long intervals can range from 2-6 miles, depending on your fitness level and goals. For you, aiming for 2-4 miles at a challenging pace (around 8:55-9:15 minutes per mile) would be a great starting point, given your goal of running a 21K in 2:00.
Why should you run a Long Interval Run?
Long intervals help your body adapt to running at a faster pace for longer periods. They improve lactate threshold. You'll build mental and physical endurance, essential for tackling longer distances. And your body becomes more efficient at using energy, making you a faster and more efficient runner. By incorporating long interval runs 2 times a week, depending on your overall training plan and recovery needs.

Ps 2:00 hours may not be your current realistic goal, but progress has always been made by wishful thinking and hard work towards achieving your target goals.
