Expert Q+A session summary:
- Incorporate weekly interval workouts: 3–5 minute intervals, 4–6 reps at 5k-10k pace. Aim for even or negative splits, targeting 95% of max heart rate.
- Example: 6 x 1000m intervals helped David lower his 5k time from 20:20 to 18:45.
- 6 x 4 minutes at marathon/half marathon pace on a 4% incline with 2–3 minutes rest.
- 8 x 1 minute on a high incline (8–10%) at a speed sustainable for 60 seconds, with 3–4 minutes full recovery.
- Calf raises (both straight and bent leg) with heavy dumbbells.
- Strengthen the foot, ankle, and shin using a theraband or towel for resistance.
- Ensure proper hydration to prevent calf cramps.
- 1 fast workout (intervals or tempo run).
- 1 long run.
- 2–3 base runs with strides or hill sprints at the end.
- Keep base runs at or below aerobic threshold and switch the long run to intervals 4–6 weeks before the event.
- Use proper running shoes to reduce injury risk, especially on hard surfaces.
- For a Zone 2 protocol, cap your heart rate at around 75% of your max (e.g., 140 bpm). Slow down or walk when you hit this cap, resuming running when your heart rate drops to 100 bpm. Start with 30 minutes and add 10–15 minutes every 2–3 weeks.
- Balance intensity and volume to avoid overtraining or stagnation.
- 4 hours of Zone 2 per week is a good baseline.
- Supplement with alactic work like strides or hill sprints to improve neuromuscular fitness without fatigue. This can be added several times a week.
- Warm up with dynamic movements like multidirectional lunges and leg swings.
- Walk for 15–20 minutes before running.
- Strengthen and mobilize the hips, glutes, and hamstrings with exercises like glute bridges and single-leg squats.
- Train in the early morning or late evening to avoid peak heat.
- You’ll adapt to training in heat, and your performance may improve when you return to cooler climates.
- Consider open-water swimming as cross-training to maintain cardio fitness while staying cool.
