Inhalation of a supratherapeutic dose of 800 µg salbutamol improved endurance cycling performance by 1.9 ± 1.8 % in non-asthmatic athletes, which indicates that this route of administration does not exclude the possibility of an ergogenic effect of beta2-adrenergic agents in athletes. https://www.thieme-connect.de/DOI/DOI?10.1055/s-2004-815716
The most important finding was that average performance time on salbutamol was reduced by 82.7 seconds – 3,927.6 seconds (65 minutes), compared with 4,010.2 seconds, a difference of just under 2%. As the researchers point out: ‘The relevance of a more than 1-minute improvement in an approximately 1-hour time trial for competitive events is obvious.’

Most of the published studies (20-22) have not been able to demonstrate increased physical performance after acute β2-adrenoceptor agonist inhalation. However, surprisingly little work has been done to determine whether oral Sal administration, which represents doses 10- to 20-fold greater, has a beneficial effect on performance. As a matter of fact, two studies (3,18) demonstrate that chronic Sal intake at therapeutic doses increases voluntary muscle strength in men, but no published information on endurance performance and on eventual hormone and/or metabolism Sal interaction(s) is available for dynamic exercise after systemic administration.

The results show that short-term oral Sal administration improves cycling performance during submaximal exercise as shown by the significant increase in time to exhaustion. The ergogenic effect of Sal observed in the present study is in disagreement with the results of most of the investigations conducted during dynamic exercise after acute Sal inhalation (20-22). The most plausible explanation is the difference in the dosage (10- to 20-fold greater per os vs. by inhalation) and in the mode of administration (acute vs. chronic).

tl;dr
Lots of it might make you faster.
