8.5 K Push

Based on your current fitness — 7,376m completed at 98 bpm avg HR with aerobic reserve remaining — you don't need a long buildup. You're already physically capable of 8,500m. The work is about extending time on water past 3:17 and adding one feed.

Do not pool swim today. Even a light pool session burns 400–600 kcal of glycogen and creates mild muscular fatigue that will show up at km 7–8 tomorrow. You spent 5 days resting to fill those stores — don't tap them 24 hours out.

Replace the Yin yoga slot with:

• 10–15 min easy walk this morning (flat, no hills)

• 10 min shoulder/hip mobility at home tonight — arm circles, hip rotations, neck rolls. That is all your body needs.

Today's only job: eat your 750g CHO, hydrate, pack gear, sleep by 9 PM.

Conditions for Jul 3 — Preliminary Assessment

FM-080 (La Jolla Shores / Avenida de la Playa) — ADVISORY ACTIVE

A water advisory was issued for FM-080 (La Jolla Shores at Avenida de la Playa) on June 24 — bacteria levels exceed health standards. This advisory may still be in effect. You must check sdbeachinfo.com directly tomorrow morning at 6 AM as part of your go/no-go. The Children's Pool (EH-310) itself has had a chronic bacteria advisory since 1997, but your start/exit point is the beach and seawall, not the pool basin.

Your start is from the open ocean side of Children's Pool — the FM-080 reading covers the La Jolla Shores corridor you will be swimming through. If FM-080 is still under advisory tomorrow, this is a go/no-go factor you need to weigh.

Surf — Watch

• NOAA surf forecast for La Jolla on Fri Jul 3: 2–4 ft, mixed swell from 280° and 220°, moderate rip current risk

• Swell Magnet confirms Jul 3 launch window: winds light/variable before 11 AM, SE offshore breeze early, stronger S/SW after noon — your 7 AM start catches the clean window

• Low tide -0.27 ft at 6:30 AM → rising flood throughout your swim (still favorable for northbound current as planned)

• Swell peaks around 11 AM — your target finish of 10:15 AM is critical. Do not extend past 10:15.

• Surf at 2–4 ft is at the upper edge of the ≤2.5 ft threshold. You will need to verify actual conditions at Children's Pool at 6 AM — the protected cove may see 1–2 ft inside the seawall even when offshore is 3 ft.

Water Temp

63°F air / water similar — wetsuit confirmed correct call.

What to Do Today (Thu Jul 2)

This is your last full day before the swim. The plan is simple and deliberate.

No additional walking, cardio, or hill sessions today. Legs need to be loaded and fresh.

Nutrition — Today (Thu Jul 2) — PEAK LOAD DAY 2

Target: 750g CHO today. This is your second and final peak glycogen loading day.

After 6 PM: water and electrolytes only. No alcohol, no heavy food, no new foods.

Tomorrow Morning Protocol — LOCKED

Gear Checklist — Pack Tonight

• Apple Watch Ultra — fully charged

• FORM Goggles Pro 2.0 — lenses clean, fit tested

• Sharkbanz — right ankle

• Wetsuit — dried and ready

• Tow float — inflated, gels loaded (8x for 55/90/110/130/150/170/190 min + spare)

• Extra Gatorade/electrolyte in car

• Dry bag with phone + post-swim clothes

• Sunscreen

Tactical Plan — No Changes Needed

The tactical blueprint stands as-is. The one update based on current conditions:

• Swell is 2–4 ft SSW — on your outbound leg heading north, the swell will be pushing slightly behind you (favorable). On return (southbound), expect 1–2 ft chop on your face side. Breathe right to avoid water entry. Stay 150–200m offshore past the cove to avoid the wave shadow zone.

• Rip current risk is moderate — stay oriented to Scripps Pier as your primary sighting target. If you feel lateral drift on the outbound, you are likely catching the rip — let it assist northward. On return, sight frequently.

• Music cue for the wall at km 7–8: your Santa Barbara 2:33 pace on Jun 27 was your fastest OW ever. That was 3,034m at pace. At km 7–8 tomorrow you will be tired — but you have trained exactly this. The second half is where 7 years of ocean swimming shows.

Summary

Today is the easiest day on paper and the most important to execute correctly. Eat your 750g, finish by 6 PM, yoga at 7:30, sleep by 9. Gear packed tonight. FM-080 check at 6 AM tomorrow is the final gate.

The conditions at 7 AM launch look workable — light winds, low tide flooding northward, swell building after 10 AM. Your window is real. Use it.

One important flag: the Jun 24 advisory for FM-080 may still be active. sdbeachinfo.com updates daily, so check it at 6:00 AM tomorrow before committing to go. If FM-080 is still red, that is a legitimate go/no-go factor — not just a technicality. You have been swimming this corridor regularly so you know your personal threshold, but the call is yours to make at 6 AM with fresh data.

Why Full Rest Jun 28–Jul 4

The Adaptation Is Already Done

Your training load over the past 6 days has been substantial:

That block — over 10.6K in 4 sessions — is the highest training density of your entire program. The stimulus is already in. More swimming now does not add fitness; it adds fatigue on top of fatigue.

What Happens During Rest

Physiological adaptation does not happen during training — it happens during recovery. The 7-day window before Jul 5 is when:

• Muscle glycogen stores fully reload (takes 48–72 hrs minimum after sustained OW effort)

• Connective tissue micro-damage from the pool block and today's OW session repairs

• Slow-twitch aerobic fibers consolidate the efficiency gains that produced 2:33/100m today

• Cortisol (stress hormone elevated by training load) drops back to baseline, which restores immune function and reduces injury risk

Arriving at the 8K with a full glycogen tank and zero residual fatigue is worth more than any additional yardage.

The Taper Math

For an aerobic event of 1.5–2.5 hours, the evidence-based taper window is 7–10 days. You are right at 7 days. One more pool session on Monday — even a light one — would cost you roughly 48 hours of glycogen recovery and connective tissue repair, landing you on Saturday not quite full. That is a measurable difference at 6K+ when the effort becomes real.

Today's Session Was the Final Signal

2:33/100m open water — your fastest pace ever — 8 days out from the attempt. That is exactly the data point you want going into a taper. It means you are in peak form right now. The job is to arrive Saturday with that form intact, not to try to build more on top of it.

The Carb Load Window

Sun Jun 29 through Fri Jul 4 is also your glycogen supercompensation window. Carb-forward meals each day (400–500 kcal, oatmeal + eggs + banana protocol) progressively top off muscle glycogen above baseline levels. This only works if you are not burning carbs through additional training. Swimming through the carb load window defeats the carb load.

Bottom line: You are ready. The data says so. Rest is the training now.

Good news — Santa Barbara looks very clean tomorrow morning.

8K Readiness — Jul 5

Well-positioned. The 625m gap from your Jun 13 PR (7,375m) to the 8K target is an 8.5% step — manageable given your PR ended with pace held and energy remaining. Ocean HR will run ~9 bpm lower than these pool sessions at equivalent pace, meaning the 8K will feel more comfortable cardiovascularly than this week's pool work did.

Fatigue Watch Points

No warning signs in this block. What to monitor going forward:

• Avg HR rising 5+ bpm at same pace on next session

• Pace reversal >5 sec/100m without explanation

• Stroke rate climbing above 46 at same pace (compensatory mechanics)

• Any shoulder or rotator tightness after today's 3,025m — at 63, connective tissue is the primary recovery priority, not cardiovascular

Bottom Line

The aerobic foundation is built. The pace convergence between your pool performance this week and your Jun 13 ocean PR is the strongest readiness signal in your entire training record. The main job between now and Jul 5 is to protect what this block built — rest Thursday, one final pool sharpener Friday, then three full rest days before the 8K. The gains are already in the system.

Energy Requirements — The Numbers

Estimated swim expenditure: ~1,200–1,400 kcal over ~130 min at MET 7.0 (your aerobic ocean pace, 65–70% VO2max). Of that, roughly 200–230g comes from glycogen — well under your loaded capacity. You are not at bonk risk if loaded correctly. The vulnerability is blood glucose in the final 30 min, which your in-swim feeding handles.

Glycogen ceiling at 75 kg, 63yo:~600–650g loaded (vs ~700g in a younger athlete — modest difference). Binding ~3–4g water per gram glycogen means you'll carry +1–2 kg on the scale after loading. That's it working.

Current Plan vs. Optimal

Your planned foods (oatmeal, rice, salmon, pasta) are mostly well-chosen, but three issues:

Refined Macro Table — Thu Jul 3 & Fri Jul 4

Thu Jul 3 — Load Day 1 (target: 700g CHO)

Fri Jul 4 — Load Day 2 / Final Carb Load (target: 750g CHO)

Switch oatmeal to cream of rice from this morning forward — lower fiber, faster gastric clearance.

Add 1 extra banana or 8oz apple juice if appetite allows to close to 750g. Dinner must finish by 6:30–7 PM — you need the 10+ hour window before the 5 AM pre-race meal.

Sat Jul 5 Morning Protocol

No solids after 6:30 AM. The reactive hypoglycemia window (large CHO bolus 30–45 min before effort) is real — don't eat a gel at 6:40 AM.

July 4 BBQ Navigation

Since it's the 4th: white potato ✓, grilled corn 1–2 ears ✓, watermelon 1–2 slices ✓, grilled chicken ✓. Ribs/brisket ✗, beer ✗, coleslaw ✗, beans ✗, spicy sauce ✗.

Key Swaps from Your Current Plan

The biggest change is volume — your current plan hits roughly 400–500g CHO/day. Getting to 700–750g requires deliberate snacking with juice, bagels, and sports drink, not just three larger meals.
