To achieve a gold star in the Blizland event of the Mario & Sonic at the Olympic Winter Games (DS), you need to perform a special dash. Here’s a step-by-step guide to help you land the special dash and earn the gold star:

### Step-by-Step Guide to Land a Special Dash in Blizland

1. **Choose the Right Character**:
– For this event, it is recommended to use Sonic or Tails due to their high speed and jumping attributes, which are crucial for performing a special dash.

2. **Start with a Turbo Start**:
– Begin your run with a turbo start. This will give you an initial boost of speed, helping you cover more ground quickly.

3. **Jump from the Red Zone**:
– Position yourself at the red zone, which is usually marked on the track. Jumping from this zone will give you an extra boost of speed and momentum.

4. **Make a Balanced Leap**:
– As you jump, aim for a balanced leap. This means timing your jump so that you land perfectly in the middle of the landing zone. A balanced leap ensures that you maintain your speed and control throughout the jump.

5. **Perfect Landing**:
– After jumping, focus on making a perfect landing. This involves landing in the middle of the landing zone without losing any speed or momentum. A perfect landing is essential for earning the gold star.

6. **Use Items Strategically**:
– If necessary, use items like Stars or Barriers to guard against obstacles that could slow you down. However, be cautious not to use items too early, as they might interfere with your timing and balance.

7. **Maintain Speed**:
– Once past the no-Ring point, boost as many times as possible with your remaining fuel to maximize your distance before the jets come off. This will help you cover more ground and increase your chances of landing a special dash.

8. **Execute the Special Dash**:
– The special dash is typically executed by performing a series of ring dashes or other high-speed maneuvers. The exact execution may vary depending on the specific event, but generally, it involves maintaining high speed and control throughout the course.

9. **Check Your Distance**:
– After completing the dash, check your distance to ensure it meets the gold star criterion. For Blizland, achieving a certain distance is crucial for earning the gold star.

10. **Practice and Perseverance**:
– Earning a gold star in Mario & Sonic at the Olympic Winter Games often requires practice and perseverance. Don’t be discouraged if you don’t succeed immediately; keep trying until you master the technique.

By following these steps and practicing your skills, you should be able to land a special dash in Blizland and earn the gold star.
