In most cases this is not personal data: it identifies a company rather than an individual, and data protection law does not apply to it.
Where the track is run by an individual and their phone number or address is also the business's, personal data is involved. The legal basis is legitimate interest (article 6.1.f GDPR): informing the public about which karting tracks exist in Spain and how to contact them.
That balancing test was written down before anything was published: these are professional contact details the track itself puts out so that people call it; they are published for that same purpose; they are limited to what is necessary; they include no special categories of data; they are not used for profiling, advertising or automated decisions; they are neither sold nor shared with anyone; and objections are handled the same day, with no explanation required. The impact on the individual is low, and the reasonable expectation of someone running a business open to the public is precisely to appear in a listing of their sector.
