The Stack
Three products targeting the three protein needs runners share: muscle repair, tendon support, and warm-weather hydration.
25g of whey isolate per scoop with minimal carbs and fat. Use within 30 minutes after long runs and tempo workouts.
See live price →18g of bioavailable collagen per serving for tendon, ligament, and joint support. Achilles, IT band, and plantar fascia recovery starts here.
See live price →20g of whey isolate in a juice-like format with under 90 calories. Refreshing in summer training when a milky shake feels wrong after a hot run.
See live price →Why This Combo
Runner protein needs differ from lifter needs in three ways.
- Connective tissue takes more abuse. Achilles, IT band, plantar fascia, knee tendons: all stressed by repetitive impact. Collagen 60 minutes pre-run with vitamin C supports tendon synthesis (Shaw et al, 2017).
- Total protein needs are still high. A 2014 study (Phillips and Van Loon) showed endurance athletes benefit from 1.2 to 1.4g/kg/day of protein, comparable to recreational lifters. Whey isolate keeps daily intake on target.
- Hot-weather training changes preferences. A milky chocolate shake after a 90-degree 10-miler isn't appealing. Clear whey gives you a cold, juice-style protein hit that feels right.
Total Monthly Cost
Math: 20 isolate servings + 30 collagen servings + 20 clear whey servings per month (assuming a moderate marathon training schedule):
| Post-run whey: Impact Whey Isolate (20 servings/mo) | $13.92/mo |
| Collagen (tendons): Collagen Peptides (30 servings/mo) | $21.42/mo |
| Clear whey (hot days): Clear Whey Isolate (20 servings/mo) | $16.00/mo |
| Total monthly cost | $51.34 |
That's about $51/month for full coverage during base building, peak weeks, and taper.
How to Use Each
MyProtein Impact Whey Isolate (post long run / hard tempo)
One scoop in water or oat milk within 30 minutes of finishing a hard run. Best for long runs (90+ minutes) and tempo workouts where muscle damage is meaningful. For an easy 30-minute jog, food is fine.
Vital Proteins Collagen Peptides (60 min pre-run)
One to two scoops in coffee or warm water 60 minutes before tendon-loading workouts (track work, downhills, hill repeats). The 60-minute window with vitamin C maximizes collagen synthesis in connective tissue.
MyProtein Clear Whey Raspberry (hot days)
One scoop in 16 oz ice water after a hot summer run. The juice-style format feels more like a recovery drink than a shake, which makes it easier to drink when you're overheating.
Cheaper Alternatives
- Swap MyProtein Isolate for Nutricost Whey Isolate at $28.95/2 lb. Same isolate form, lower brand price.
- Swap Vital Proteins for Sports Research Collagen at $29.99/1 lb.
Upgrade Path
- Upgrade whey to Transparent Labs Grass-Fed Whey Isolate for cleaner sourcing and no artificial sweeteners.
- Upgrade clear whey to BPN Strong Reformer Clear Whey with added L-carnitine, which has weak but interesting evidence for endurance recovery.

See runners' guide →Frequently Asked Questions
Recreational runners doing 20 to 40 miles per week need around 0.6 to 0.8g of protein per pound of bodyweight (130 to 175g for a 165 lb runner). Marathon trainers and ultra runners often benefit from 0.9 to 1.0g/lb during peak weeks. This stack covers around 50 to 60g of that daily target.
For prevention and joint maintenance, the evidence is reasonable. Shaw et al (2017) showed 15g of gelatin + 50mg vitamin C taken 60 minutes pre-training doubled collagen synthesis in connective tissue. The effect on existing injuries (rehab) is less clear, but it's safe and cheap to try.
Purely a quality-of-life pick. Regular whey works fine. Clear whey just feels better post-run on hot days because it's cold, light, and juice-like rather than heavy and creamy. If you train indoors year-round, you can probably skip it.
Yes, if you need it to hit your daily protein target. Muscle protein synthesis runs continuously, not just on training days. Hitting your daily protein number on rest days is just as important for adaptation as on training days.
Yes. Whey isolate has minimal carbs (under 2g per scoop), so it doesn't interfere with carb-loading. Collagen has effectively zero carbs. Clear whey has under 1g per serving. You can take all three during a carb-load week without affecting your glycogen target.
Don't use protein powder during a race. Stick to gels, chews, and sports drinks for the race itself. Protein powders are recovery tools, not in-race fuel. Pre-race breakfast can include a small protein shake 3 hours before the gun, but don't experiment on race day with anything new.
