Intro: This is a quick summary of How well do you know your body? from This Messy Happy. It’s a fun watch — we’re breaking it down so you can try the blind challenges today. Be sure to check out the full video for all the details.

Key Points:

• The “blind” concept means running without checking your watch, forcing you to trust your body’s feel for pace and effort.
• Five progressive challenges cover base pace consistency, VO₂‑max intervals, progressive pace drops, heart‑rate zone work, and a tempo run.
• Scoring is simple: each second you’re off the target adds a point; the goal is zero points.
• Warm‑up (1‑3 km) and cool‑down (1‑3 km) are included in every session.

Workout Example (Challenge 1 – Blind Base 5 km):

1. Warm‑up: run 1–3 km at an easy pace.
2. Run 5 km blind – aim to keep every kilometre at the same pace. If you’re new, check your watch after the first kilometre to set the target, then run the remaining 4 km without looking.
3. Cool‑down: 1–3 km easy.

• Target pace: e.g., 5:00 min/km for each kilometre. Every second you’re faster or slower adds a point (5:01 = 1 point, 4:59 = 1 point, etc.).

Other Challenges (quick reference):

• Blind VO₂‑Maxer: 4 × 1 km at 5 k pace or faster, each round separated by 4 min recovery. Match the time of the first kilometre on the return leg.
• Blind Steps to Hell: 1 km at easy base (e.g., 5:00 min/km), then drop pace by 20 s each km (4:40, 4:20, 4:00, 3:40) without looking at the watch.
• Heart‑Lek: Zone‑based set – 4 min in Zone 2, 3 min in Zone 3, 2 min in Zone 4, 1 min in Zone 5, then 5 min walk; repeat twice. Keep average HR within the target zone for zero points.
• Blind Tempo: After warm‑up, run 20 min at your tempo heart‑rate (high Zone 3, ~170 bpm) or half‑marathon pace, without checking the watch.

Closing Note: Give these blind challenges a go and see how well you can trust your body’s signals! You can easily adjust the paces to fit your own training using the Pacing app. Have fun, score zero points, and let us know your results – then keep running happy!
