⛰️ Climb Challenge Ratings

R5m evaluates route elevation profiles using two distinct rating methodologies: FIETS Mode and A2 Mode.
🔗 FIETS Reference & Climb Challenge Details
FIETS Mode (Default): Calculates physical exertion (suffer score) based on total climb gain, overall distance, and high-altitude bonuses above 1,000m (3,281 ft).
A2 Mode: Measures peak gradient severity by analyzing sustained rolling 100-meter (328 ft) segments along each ascent.
FIETS Score Equation
Score = (Gain_m² / (Dist_m × 10)) + max(0, (PeakAlt_m - 1000) / 1000)
Difficulty Ranking Thresholds
Rating FIETS Score A2 Avg Grade
Easy < 0.25 < 3.0%
Steady 0.25 – 0.49 3.0% – 6.9%
Stiff 0.50 – 0.99 7.0% – 9.9%
Brutal 1.00 – 1.99 10.0% – 12.9%
IHEFC ≥ 2.00 ≥ 13.0%
Normalized Severity (NS) Score
Ranks each climb relative to the easiest and hardest climb on the current route (0.00 to 1.00). Badges are color-coded: Green (<0.25), Orange (0.25–0.49), Red (0.50–0.74), and Purple (≥0.75).

🏁 Basic Operation

Select or import a ride route to instantly calculate distance, elevation profile, logistics schedule, weather forecast, and clothing layering recommendations:

🚴 Ride Selector Button Tap the Cyclist (🚴) icon in the top right header to open the Ride & Route Selector. This searchable catalog lets you browse club rides with terrain filters, distance, elevation profiles, and RideWithGPS links. Selecting any ride loads its route directly into R5m.
📋⭐ Favorites List Button Tap the List + Star (📋⭐) icon in the top right header to access your Favorite Rides. Star any ride inside the Ride Selector to bookmark it for 1-tap loading without searching the full catalog again.

⚡ Route Override

Toggle Override to manually set custom distance, elevation, and meet ZIP code without loading a RideWithGPS URL.

📅 Logistical Timings

R5m automatically calculates all 7 logistics milestones based on your Meet Time, driving duration, rollout buffer, and ride pace:

Wake: Recommended wake-up alarm (45 minutes before Home Departure, rounded to nearest 5 mins).
Depart: Estimated home departure time (Meet - Drive Time).
Meet: Planned arrival / staging time at the ride start location.
Roll: Wheels-rolling rollout time (Meet + Rollout Buffer, default 20 mins).
Finish: Estimated ride finish time (Roll + Total Ride Duration).
Egress: Departure time from ride site after post-ride pack-up (Finish + Rollout Buffer).
Home: Estimated arrival time back home (Egress + Return Drive Time).
🚗 Driving Time Engine & Methodology

R5m computes your driving travel times for both legs of your journey (Home → Ride Start and Ride Finish → Return Location) using predictive real-time traffic data:

Google Maps Routes API (Primary): By default, R5m queries Google Maps Routes v2 with traffic awareness for your exact departure date and time-of-day.
P80 Conservative Risk Modeling: Google returns a duration range from \(P_{10}\) (optimistic, free-flow) to \(P_{90}\) (pessimistic, congested). R5m uses the P80 percentile (80th percentile) to ensure you arrive comfortably on-time for morning rollout without over-inflating your wake-up alarm.
OSRM Routing Fallback: If Google Maps is unreachable, offline, or quota-constrained, R5m seamlessly degrades to OpenStreetMap (OSRM) with localized historical time-of-day multipliers so timeline calculations are never interrupted.
Timeline Engine Badges: In the Meet/Timeline detail popup, the badge in the lower-right indicates the active calculation source:
GMAPS Powered by Google Maps predictive traffic.
FALLBACK Google service unavailable; active on OSRM.
OSRM Baseline OpenStreetMap routing.
