"Twelve Seconds On A 21-Kilometre Climb Is Either A Big Margin Or No Margin At All — Saturday Morning Will Tell Us Which" — Tour Of Turkey 2026 Stage 6 Feslıkan Friday-Night Final Briefing, Cofidis Authorise A Two-Rider Morning-Break Stack, MGM Holds The 11°C Summit Forecast, A 13-Degree Coastal-To-Altitude Thermal Swing Is The One Variable The Books Cannot Price
Friday night Antalya. Twelve hours from the 11:35 local flag drop on the 127.9km Antalya–Feslıkan queen stage of the 2026 Tour of Turkey, and the Friday-night betting-market lock on Stage 6 has resolved into a four-way GC cluster behind a Sosa price the books have refused to drop below 4/9 outright across the closing day of trading. Sosa at Kern Pharma defends 12 seconds over Samitier at Cofidis, with Pescador at +28" and Fortunato at +34" the next two priced threats; Dunbar at +51" the outside podium hope. The 21km/8.4% Feslıkan summit at 1,900m altitude is the only structural variable left.
Take the GC numbers first. Sosa wins the Tyrone TT-equivalent stage — the stage 1 Marmaris-Datça TT — by 11 seconds over Samitier and rode through the four flat days that followed without losing a metre on any of the priced threats. Kern Pharma's Friday-evening operations brief out of the Antalya hotel has Sosa riding wheel-to-wheel with Samitier through the lower 11km of the Feslıkan and then making his decision at the second switchback above the 1,400m line — a number Kern Pharma DS Mikel Astarloza confirmed at the Friday-evening team briefing was set on Wednesday morning during the closing recon. The 12-second margin is not big enough to absorb a Cofidis-style two-rider relay drop without a response, and Astarloza has built that response into the stage plan rather than waiting to react to it.
The Cofidis tactical stack is the second story. The Friday-night team briefing out of Cofidis confirmed two riders into the morning break — most-likely Champoussin and Martin — with the explicit brief to peel off the front group and act as relay-drop riders for Samitier on the lower slopes of the Feslıkan. The break window opens in the first 25km of the valley run-out from Antalya; the closing 21km of climbing has no flat section to recover on, no descent to draft on, and no echelon scenario to play with. Cofidis's tactical stack is the only structurally viable way to take 12 seconds out of Sosa across a 21km solo climb — and the Friday-night Antalya hotel briefing has the team committed to it. Martínez the most-likely Pescador-line counter; Soler riding free for stage hunting after his GC bid collapsed on Stage 4.
The third strand is the weather. Friday-evening MGM bulletin holds the summit forecast at 11°C with light south-westerly force-2 wind, valley start at 24°C, the 13-degree thermal swing across the climb the largest of the spring calendar bar Stage 4 of the Vuelta a Andalucía in February. The 1,900m altitude line passes through 1,400m and 1,650m altitude bands that the riders have not raced through in 2026 — Pescador in particular has not ridden above 1,500m in a race since the 2024 Vuelta, and the Friday-night Equipo Pescador briefing has flagged the altitude as the variable that could move the book. Sosa's Friday-night response: "I lived in Madrid at 700m for ten years. Twelve hundred metres above that is a number, not a problem." Samitier's response: "I trained on the Pico de Veleta last week. The number does not concern us."
The book. Sosa 4/9 outright across all five major UK exchanges. Samitier 4/1, Pescador 12/1, Fortunato 14/1, Dunbar 33/1. Stage book: Cortina 8/1 the most-likely breakaway-survivor stage call, Paret-Peintre 12/1 stage-hunting after Liège, Soler 14/1 free-rolling after Stage 4 abandonment, Van Baarle 16/1 the long-shot. The four-way GC cluster shortens at every Friday-night exchange — the only honest reading of the closing day's market is that the books expect Sosa to defend.
The Stage 6 operational stack. Flag drop 11:35 Antalya, expected line at Feslıkan 15:30, the Friday-night TRT Spor schedule has dedicated coverage from 13:00 with a 90-minute pre-race window. The valley run-out from Antalya to the base of the climb is 65km of largely flat road on the D330; the closing 21km gain 1,790m to the summit, a climb only finished by Sosa once before in 2024 when he rode 49:50. The 49:50 number is the Friday-night benchmark — anyone who beats it without 35 seconds of help from a relay drop will be the GC winner. Cofidis's stack is built around the help.
The bigger picture. Tour of Turkey closes Sunday with a flat run-in to Istanbul; the GC will be locked on the Feslıkan summit Saturday afternoon. Race director Açıkalın at the Friday-evening press conference confirmed the 2027 calendar slot will move forward by a week to mid-April to avoid Romandie, a slot that has cost the race four WorldTour entries in 2026 and is the underlying reason Sosa is racing here at all. The 2026 startlist quality has dropped by 17% on 2025; the 2027 calendar move will recover roughly 11% of that according to UCI's own internal projection, and the Friday-night ProCycling Council read had the calendar move as the single most consequential 2027 decision on the spring stage-race book. Saturday is the day that decision gets a result on its side.
Twelve seconds on a 21km climb. Cofidis stacking the break. MGM holding 11°C and a 13-degree thermal swing. Sosa riding wheel-to-wheel until 1,400m altitude, then making his decision. The Friday-night Antalya operations stack is locked. Sosa at the team-hotel press call: "I have ridden this climb four times in training and once in a race. Tomorrow is the fifth time. The numbers are good. The legs are good. The plan is clear." Flag drop 11:35 local Saturday morning.
