# How to fuel for a PR on your local route, with Claude, Strava and Forkmate

Fuel a personal best on your usual loop: Claude reads past efforts via Strava's connector and your Forkmate food log, then plans the fuel. Prompts inside.

**Short answer:** a personal best on a route you ride or run all the time is mostly about pacing and training, but fuel can make a difference near the end. For an effort of about an hour, eat a familiar, carb-forward meal 1–4 hours before (1–4 g of carbohydrate per kg of body weight), start hydrated, and use small amounts of carbohydrate or a mouth rinse during if it runs past about 45 minutes [S1, S2]. With **Strava’s connector** and **Forkmate** both connected to Claude, you can ask Claude to look at your past efforts on the route and what you’ve eaten over the last few days, then plan around foods you already eat.

## What’s connected to what

- **Forkmate** is a free food log you fill in by telling your AI app what you ate. Connecting it to Claude takes about two minutes; the steps for every app are on the [connect page](https://forkmate.ai/connect/). Through it, Claude can read a day (`get_day`) or a date range (`get_range`) of your diary, see your most-logged foods (`get_usual_foods`) and log a meal when you ask (`log_meal`).
- **Strava** publishes its own official Claude connector. In Claude it’s under **Customize → Connectors**; it’s read-only, and it needs a paid Strava subscription. Strava’s help article lists activity history, fitness trends, readiness, goal planning, cross-sport training and gear ([Strava’s help article](https://support.strava.com/hc/en-us/articles/46190267796237)). It doesn’t mention segments or saved routes, so point Claude at past activities on your route by name or date.
- **Garmin** has no official Claude connector. If your Garmin activities upload to Strava, Claude sees them there; otherwise, describe the route and your best time in the chat.

**Forkmate has no link to Strava or Garmin.** Claude reads your activities through Strava’s connector, and Forkmate only holds the food you ask it to log. Forkmate doesn’t count exercise calories or change your goal for training. Claude does the side-by-side.

## Example: “Help me fuel for a PR on my local route”

*This is an illustrative example: a fictional rider, Alex, 70 kg, with made-up numbers. It follows the shape of a real conversation, not anyone’s real data.*

Help me fuel for a PR on my local route. It’s my “River loop” on Strava, about 40 km. I’m going for it Saturday morning. Check my past efforts on it and what I’ve been eating in Forkmate.

Here’s what Claude did, in order:

1. **Found the past efforts.** Through Strava, it found eight rides named “River loop” over the previous three months. The fastest was 1 hour 12 minutes; most were 1:15–1:20. So a PR attempt meant about 70 minutes of hard riding.
2. **Read the recent diary.** Through Forkmate’s `get_range`, it read the previous five days. Three were fully logged, and two had only breakfast. On the fully logged days, carbohydrate was about 3–4 g per kg, at the light-training end of the daily ranges [S2]. Claude said it couldn’t judge the two partial days and didn’t count them as low. It suggested making Friday’s meals carb-forward and familiar, not unusually large.
3. **Planned the fuel around Alex’s own foods.** Using `get_usual_foods`, it built from what Alex logs most:

  - **Friday dinner:** a usual pasta dinner, nothing new.
  - **2–3 hours before:** about 1 g of carbohydrate per kg, so roughly 70 g: two slices of white toast with a tablespoon of honey and a medium banana, about 72 g [S2, S6]. Lower in fat and fibre than usual so it sits easily.
  - **Before the start:** fluids with breakfast, about 5–10 mL per kg in the 2–4 hours before (350–700 mL for Alex) [S2]. A warm-up, then go.
  - **During:** at about 70 minutes, the ranges say a mouth rinse or small amounts of carbohydrate may help a hard effort [S1, S2]. One bottle of a sports drink Alex has used before covers both, plus water if it’s hot.
  - **After:** a normal meal with carbs and 20–40 g of protein [S4].
4. **Offered to log it.** When Alex said yes to the breakfast, Claude logged it to Forkmate with `log_meal`.
5. **Kept fuel in its place.** It noted that a PR on a known loop also depends on wind, traffic and pacing, and that the plan works best if Alex tries the breakfast before a training ride first.

**If your route is shorter.** A 5 km run PR or a 25-minute bike loop needs no carbohydrate during: under about 45 minutes, the ranges say none is needed [S2]. The pre-effort meal and fluids are what matter.

## The ranges behind the plan

### Before

- **1–4 g of carbohydrate per kg, 1–4 hours before** [S2]. For a hard effort, many people go for the low end, about 1 g/kg, 2–3 hours out, so the meal sits easily. For a 70 kg rider, that’s about 70 g: a slice of white toast is about 14 g, a tablespoon of honey about 17 g and a medium banana about 27 g [S6].
- **Fluids:** about 5–10 mL per kg in the 2–4 hours before leaves time to absorb it and to pass any extra [S2].
- **Nothing new.** Use a breakfast and a drink you’ve tried before a hard training session.

### During

| Effort length | Carbohydrate | Source |
| --- | --- | --- |
| Under 45 minutes | None needed | [S2] |
| 45–75 minutes | A mouth rinse or small amounts may help a hard effort | [S1, S2] |
| 1–2.5 hours | About 30–60 g per hour | [S2] |

**Fluids:** sweat rates vary a lot between people. The ACSM aims to keep fluid losses under **2% of body weight**; weighing yourself before and after a training ride or run shows your own rate [S3]. Don’t drink so much that you gain weight over the effort [S2, S3].

### After

- **Protein:** about 0.25 g per kg, or 20–40 g, at the next meal [S4].
- **Carbohydrate:** if you train hard again within about 8 hours, 1.0–1.2 g per kg per hour for the first 4 hours [S2]. Otherwise, normal meals usually cover it.

## Copy-paste prompts

Use these in a Claude chat with both Forkmate and Strava’s connector turned on. Swap in your route name, weight and day.

>

Help me fuel for a PR on my local route. It’s the activity I call “[route name]” on Strava. Find my past efforts on it, tell me how long a PR attempt would take, then read the last 5 days of my Forkmate diary and plan what to eat the evening before, the morning of, and during. I weigh [X] kg. Use foods I log often.

>

Read my Forkmate diary for the last 5 days. Which days are fully logged? On those days, roughly how many grams of carbohydrate per kg did I eat? I weigh [X] kg. Don’t count partly logged days.

>

I’m attempting a PR on “[route name]” at [time] tomorrow. Plan a breakfast with about 1 g of carbs per kg, 2–3 hours before, from foods I’ve logged before, and log it to Forkmate when I say yes.

>

I finished my PR attempt on “[route name]”. Pull the activity from Strava, then help me plan a recovery meal with 20–40 g of protein and log it to Forkmate when I confirm.

## A note on safety

These ranges come from position statements written for athletes in general. They’re starting points to adjust to your gut, body and training, not prescriptions. Forkmate is a general-wellness tool, not medical advice. If you have diabetes or another medical condition, a history of disordered eating, or specific performance goals, work with a doctor or a registered sports dietitian. If the numbers ever start to feel heavy, Forkmate’s **calm mode** hides them everywhere while still keeping what you log.

## The recap

1. **Connect Forkmate and Strava’s connector in Claude.** They never talk to each other directly; Claude reads both.
2. **Ask Claude to find your past efforts** on the route, so the plan matches how long the attempt will take.
3. **Before:** 1–4 g/kg of carbs, 1–4 hours out, and start hydrated [S2].
4. **During:** nothing under 45 minutes; a mouth rinse or small amounts at 45–75 minutes [S1, S2].
5. **After:** carbs and 20–40 g of protein at the next meal [S4].
