Also this weekend
San Francisco is currently a pro-only T100 stop. There is no T100-branded age-group or amateur race here, unlike venues such as Vancouver or Qatar that combine pro and age-group racing the same weekend. The closest amateur opportunity in the same city is the separate, 46-year-old Sokin Escape From Alcatraz Triathlon (1.5-mile swim / 18-mile bike / 8-mile run) — it is not part of the T100 series, uses its own random-drawing lottery for entry, and in 2026 ran the day after the pro T100 race (Sunday 7 June, versus the pro race's Saturday 6 June).
Leg 1 of 3
Swim — 2km
Pro athletes jump from a boat into San Francisco Bay near Alcatraz Island for a roughly 2km swim to shore. The race leans hard on the 46-year-old Escape From Alcatraz Triathlon's course and mystique for marketing, but the two events are not the same distances: T100's pro split (2km/80km/18km) is the standard T100 format, not the legacy amateur race's own 1.5-mile/18-mile/8-mile course. Treat them as two different races sharing an iconic setting and, from 2026, a shared title sponsor (Sokin) — not one race under two names.
- Venue
- San Francisco Bay, off a boat near Alcatraz Island
- Elevation gain
- No official figure published — see notes above
- Surface
- Sea — open water, San Francisco Bay. Cold, with strong currents typical of this stretch of the Bay.
Wetsuit: Not published specifically for the T100 pro race. Applying the general T100/World Triathlon banding used at other venues (mandatory below 15.9°C, prohibited above 24.6°C) against San Francisco Bay's typical June water temperature — commonly cited around 12.9-15.4°C (roughly 55-60°F) — a mandatory wetsuit swim looks near-certain. The separate amateur Escape From Alcatraz race, in the same water at the same time of year, states 55°F (about 12.8°C) and describes wetsuits as 'recommended' rather than formally mandatory, which is a slightly different framing worth noting rather than assuming carries over to the T100 pro rule.
Leg 2 of 3
Bike — 80km
Six laps of a roughly 8.5-mile (13.7km) loop through the Presidio's hills — the same hilly terrain used by the Escape From Alcatraz course — passing beneath the Golden Gate Bridge. This is a genuinely hilly T100 course, unlike the flat city-street venues (Doha, Vancouver's flat sections) elsewhere on the calendar.
- Venue
- The Presidio, San Francisco
- Elevation gain
- No official figure published — see notes above
- Surface
- Closed/marshalled road — hilly, real climbing on every lap.
Non-drafting
Leg 3 of 3
Run — 18km
Four out-and-back laps along Crissy Field on gravel paths after T2, finishing on a short grassy section near the Bay — flat compared with the bike leg, with views back toward the Golden Gate Bridge.
- Venue
- Crissy Field, San Francisco
- Elevation gain
- No official figure published — see notes above
- Surface
- Gravel path — flat, waterfront.
Transitions
A single transition area serves both T1 and T2 in the Marina Green/Crissy Field vicinity, inferred from the run course finishing there — the organiser hasn't published an exact transition location separate from the wider venue.

Where T100 San Francisco starts and finishes
T100 San Francisco starts at San Francisco Bay — Marina Green / Crissy Field / Presidio area (the organiser has not named an exact swim, transition or finish site separate from the wider Escape From Alcatraz venue) and finishes at San Francisco Bay, off a boat near Alcatraz Island. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on. The official course map is the one to use: view it on the organiser's site .
What you can qualify for
Doesn't currently apply here. T100's Qatar Age-Group World Championships qualification pathway runs through T100 age-group mass-participation races (a top-10 age-group/gender finish qualifies), and San Francisco has no such race — it's pro-only. There is nothing to qualify through at this venue.
Entry & Ballot
Direct entry summary
There is no T100 entry to buy here — San Francisco is pro-only within the T100 series, and spectating the pro race is free and open to the public. The 2027 edition is dated 5-6 June 2027 on T100's own schedule page. If you want to actually race a triathlon in San Francisco, the route in is the separate Escape From Alcatraz Triathlon (see below), not T100.
Ballot policy
No T100 ballot exists — this is a broadcast/spectator race for age-groupers, not an entry race.
Age requirement
Not published for this event — there is no T100 age-group race here to set a minimum age for. (The separate Escape From Alcatraz amateur race has its own entry rules, unrelated to T100.)
Charity Places
No T100 charity-place scheme has been published for San Francisco. (The separate Escape From Alcatraz race does run its own charity-partner entry route, outside the T100 series.)
Race Day Info & Checklist
On the day
- In May 2026, the PTO announced a Sokin-branded rename tying both races together: the pro race became the 'Sokin San Francisco T100 Triathlon' and the legacy amateur race became the 'Sokin Escape From Alcatraz Triathlon' — a shared title sponsor, not a merged event. The two still run on different days, at different distances, with different entry systems.
- The bike course uses six laps of the Presidio's hills and the run four laps of Crissy Field — a genuinely technical, hilly T100 venue by series standards, in contrast to the flat closed-road circuits typical elsewhere on the calendar.
- The Escape From Alcatraz weekend (which the pro race sits inside) brings real road and transit disruption to the Marina/Presidio area: in 2026, SFMTA closed the northernmost lanes of Marina Boulevard between Scott and Lyon Streets from 3:00am to 4:30pm, with rolling street closures 6:30-10:30am as the amateur race passed through. Whether the Saturday pro race carries its own, separate closure schedule hasn't been published — this detail is drawn from the Sunday amateur race and should be treated as the best available proxy, not a confirmed pro-race schedule.
- General T100-wide prize money for a regular-season World Championship Tour stop was $275,000 in 2026 (top-20 payout), with a separate $725,000 per-gender bonus pool tied to season-long "Race to Qatar" standings — not confirmed as San-Francisco-specific figures.
- Because there is no T100 age-group race here, the usual Qatar T100 Age-Group World Championships qualification pathway (top-10 age-group/gender finish at a T100 mass-participation race) does not currently apply at this venue — there is nothing to qualify through at San Francisco itself.
Checklist
- Warm, wind-resistant layers if watching in person — June mornings at Marina Green/Crissy Field are typically foggy and cold off the Bay
- A spot along Marina Green or Crissy Field staked out early; parking directly at Marina Green is not permitted during the wider race weekend and vehicles are towed
- Public transit, a bike, rideshare or a drop-off rather than driving yourself in — the Escape From Alcatraz weekend logistics strongly discourage parking near the venue
- A plan to livestream if you can't be there — TriathlonLive.io, the T100 YouTube channel and regional broadcasters (Eurosport, Sky Sports, Peacock among others) all carried the 2026 race
- If you actually want to race a triathlon in San Francisco rather than watch one: look at the separate Escape From Alcatraz random-drawing lottery, which is a different entry system entirely from T100
Transport, Spectating & Where to Stay
Transport
No dedicated rail service reaches Marina Green/Crissy Field. Muni bus routes 22, 30 and 45 serve the Marina area and are the routes cited for the adjacent Escape From Alcatraz weekend.
No parking is permitted at Marina Green or on Marina Boulevard during the wider race weekend — vehicles in restricted areas are towed. The Palace of Fine Arts lot is the nearest recommended parking for the amateur race weekend; whether the same applies to the Saturday pro race specifically hasn't been separately confirmed.
Not separately published for the Saturday pro race. For context, the Sunday 2026 amateur race closed Marina Boulevard's northernmost lanes between Scott and Lyon Streets from 3:00am-4:30pm, with rolling closures 6:30-10:30am as the race passed through.
Spectator guide
Marina Green is the best-established viewing spot — it covers the swim finish area, transition, and both sides of the finish chute for the adjacent amateur race, and is likely to offer similar views of the pro race given the shared venue. The Presidio bike loop and Crissy Field run laps give repeated views of athletes on course.
Muni buses 22, 30 and 45 reach the Marina area; walking, cycling or rideshare is recommended over driving given the parking restrictions.
Where to stay
Marina District
+ Walking distance to the swim finish, transition and finish line at Marina Green/Crissy Field.
– A small, high-demand neighbourhood on race weekend — book early.
Fisherman's Wharf / North Beach
+ A short rideshare or bus ride from the venue, with a much wider range of hotels.
– Not walkable to the venue on race morning.
Presidio / Cow Hollow
+ Close to the bike course and generally quieter than downtown.
– Fewer hotel options than central San Francisco.
Frequently Asked Questions
Can I enter T100 San Francisco as an age-grouper?
No — San Francisco is currently a pro-only T100 stop with no age-group entry. The separate, much older Escape From Alcatraz Triathlon in the same city is the closest amateur option, but it is not part of the T100 series and has its own distances and lottery entry.
Is T100 San Francisco the same race as Escape From Alcatraz?
No, despite sharing a course setting, a June weekend, and (since 2026) a Sokin title sponsor. The T100 pro race runs the standard T100 distances (2km/80km/18km) on the Saturday; the 46-year-old amateur Escape From Alcatraz race runs its own distances (1.5-mile/18-mile/8-mile) on the Sunday, via a separate random-drawing lottery entirely outside the T100 series.
When is T100 San Francisco 2027?
5-6 June 2027, per T100's own schedule page. Exact 2027 start times have not been published yet; the 2026 race started at 06:35 PDT after a 06:30 PDT broadcast start.
What is the T100 San Francisco course like?
A 2km boat-start swim in San Francisco Bay near Alcatraz Island, a hilly 80km bike (six laps of the Presidio, passing beneath the Golden Gate Bridge), and an 18km run (four laps of Crissy Field on gravel), finishing on a grassy section near the Bay.
Do pros wear wetsuits at T100 San Francisco?
Not officially stated for the pro race specifically, but very likely given typical June Bay temperatures of roughly 12.9-15.4°C — well inside the general T100 mandatory-wetsuit band of below 15.9°C. This is an inference from general banding and typical water temperatures, not a confirmed race-specific rule.
Does T100 San Francisco count toward the Qatar T100 Age-Group World Championships?
Not currently — that qualification pathway runs through T100 age-group mass-participation races, and San Francisco doesn't have one. It doesn't apply here unless that changes.
How do I watch T100 San Francisco?
Free via TriathlonLive.io, the T100 YouTube channel, and regional broadcast partners (Eurosport, Sky Sports and Peacock among those carrying the 2026 race). In person, Marina Green and the Crissy Field run course give the best views.
Is there parking near T100 San Francisco?
Not at the venue itself — Marina Green and Marina Boulevard have no parking during the wider race weekend and towing is enforced. Public transit, cycling or rideshare are the recommended ways in.
When were T100 San Francisco results published?
Results are published shortly after each race on the PTO stats portal. 2026 results are already live; check back here, or the official results source, once the 2027 race has taken place.
