Chianti Ultra Trail by UTMB 2027

Entry is first come, first served through UTMB, with no lottery. UTMB Index holders had a 48 hour head start from 3 June 2026, and from 5 June it opened to everyone until 27 February 2027 or until each race sells out. There's no waiting list, and the marathon has already sold out. The organizer says the event has sold out since its first edition. Start waves are set by UTMB Index, and without one you start in the last wave.

To collect your bib you need a medical certificate that meets Italian law. You also need personal accident insurance that covers search and rescue in Italy, which the entry fee doesn't include. Entries can't be transferred or deferred, and without the cancellation insurance there's no refund. You can move to a shorter race up to four weeks before, if it has room. Runners aged 18 or 19 can't enter the 120 or the 73.

Radda is a small hilltop village about 50 km from Florence and 30 km from Siena, by the organizer's figures. Florence airport is about an hour's drive, Pisa an hour and a half and Bologna just under two. The nearest train stations, Montevarchi and Figline Valdarno, are 25 and 35 minutes away by car, with no bus to Radda from either, only taxis. Buses run to Radda from Florence and Siena but not on Sundays, and Saturday service may be limited. Buy the ticket before you board.

Parking in Radda is limited, and the organizer recommends its shuttles. In 2026 it ran paid shuttles from Villa Costanza in Florence, which you reach by tram from the airport or Santa Maria Novella station, and they had to be booked ahead. For 2027 it plans shuttles to the start for the races that leave from Radda, and back to Castellina and Gaiole after the marathon and the half. Booking will be required and opens in 2027.

Only the 120 and the 73 have crew access, and only at the aid stations marked as assistance points: Brolio, Monteluco, Cantalici, Gaiole, Albola and San Michele on the 120, and Albola and San Michele on the 73. Each runner gets one supporter, no ticket needed, and the zone runs from 500 m before the aid station to 500 m after. You can go in 15 minutes before your runner is due and hand over clothes and food that fit in a bag of about 30 liters. Outside those zones, nobody may help you.

There are no pacers: supporters may not run with their runner outside the marked zones near the aid stations. The organizer runs shuttles for supporters following the 120 and the 73, booked ahead. The free LiveTrail app shows your runner's last checkpoint and estimated times for the next ones.

The race comes at the start of spring. Siena, at 322 m, averages highs of 14.6°C and lows of 5.3°C in March, with rain on 7 or 8 days, by the 1991 to 2020 normals. Radda is higher, at about 530 m, and San Michele, the highest aid station, is at 847 m.

For the 120 and the 73, the 2027 kit list asks for two working headlamps with backup power for each, a hooded waterproof jacket with sealed seams, and full-length tights. You also need a running pack, a phone with LiveTrail and roaming, 1 liter of water, a cup of at least 15 cl (bottles and flasks with lids don't count), a survival blanket, a whistle, a food reserve and ID. The 46 needs the same minus the lamps, jacket and tights. If the forecast calls for it, the organizer can add items such as a warm layer, waterproof overtrousers and 2 liters of water, and tells runners before bib collection opens.
