According to an example aspect of the present invention, there is provided an apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to determine a predicted user activity type based at least partly on a thematic map database and a current location of the apparatus, present the predicted user activity type as a suggested activity type to a first user, and responsive to the first user approving the suggested activity type, initiate an activity session of the suggested activity type.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. An apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to: determine a predicted user activity type based at least partly on a thematic map database and a current location of the apparatus; present the predicted user activity type as a suggested activity type to a first user, and responsive to the first user approving the suggested activity type, initiate an activity session of the suggested activity type, provide a recording of the activity session, the recording comprising information on at least one of the following: a route taken during the activity session, a metabolic rate or metabolic effect of the activity session, a quantity of energy consumed during the activity session, a sound recording obtained during the activity session and an elevation map along the route taken during the activity session. 2. The apparatus according to claim 1, wherein the thematic map database comprises a heat map. 3. The apparatus according to claim 1, wherein the thematic map database associates past indications of activity type with geographic locations where the past indications of activity type have been made. 4. The apparatus according to claim 3, wherein the past indications of activity type have been made by a plurality of users. 5. The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processing core, cause the apparatus to determine the predicted user activity type based at least partly on at least one of the following: a season of the year, a time of day, an output of an acceleration sensor, user settings of the first user and history information of the first user. 6. The apparatus according to claim 5, wherein the acceleration sensor is comprised in the apparatus. 7. The apparatus according to claim 5, wherein the apparatus is configured to receive the output of the acceleration sensor from a personal device of the user. 8. The apparatus according to claim 7, wherein the apparatus is configured to receive the output of the acceleration sensor via a short-range wireless interface arranged between the apparatus and the personal device of the user. 9. The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processing core, cause the apparatus to determine the predicted user activity type at least partly by transmitting a query to a thematic map database server, the query comprising an indication of the current location of the apparatus. 10. The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processing core, cause the apparatus to modify a display provided to the first user based at least partly on the predicted user activity type prior to the first user approving the suggested activity type. 11. The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processing core, cause the apparatus to determine the predicted user activity type based at least partly on presence of sensor information originating in an activity type specific sensor. 12. A method comprising: determining a predicted user activity type based at least partly on a thematic map database and a current location of an apparatus; presenting, by the apparatus, the predicted user activity type as a suggested activity type to a first user; responsive to the first user approving the suggested activity type, initiating an activity session of the suggested activity type, and providing a recording of the activity session, the recording comprising information on at least one of the following: a route taken during the activity session, a metabolic rate or metabolic effect of the activity session, a quantity of energy consumed during the activity session, a sound recording obtained during the activity session and an elevation map along the route taken during the activity session. 13. The method according to claim 12, wherein the thematic map database comprises a heat map. 14. The method according to claim 12, wherein the thematic map database associates past indications of activity type with geographic locations where the past indications of activity type have been made. 15. The method according to claim 14, wherein the past indications of activity type have been made by a plurality of users. 16. The method according to claim 12, wherein the predicted user activity type is determined based at least partly on at least one of the following: a season of the year, a time of day, an output of an acceleration sensor, user settings of the first user and history information of the first user. 17. The method according to claim 16, wherein the acceleration sensor is comprised in the apparatus. 18. The method according to claim 16, further comprising receiving, in the apparatus, the output of the acceleration sensor from a personal device of the user. 19. The method according to claim 18, further comprising receiving the output of the acceleration sensor via a short-range wireless interface arranged between the apparatus and the personal device of the user. 20. (canceled) 21. (canceled) 22. (canceled) 23. (canceled) 24. A non-transitory computer readable medium having stored thereon a set of computer readable instructions that, when executed by at least one processor, cause an apparatus to at least: determine a predicted user activity type based at least partly on a thematic map database and a current location of the apparatus; present the predicted user activity type as a suggested activity type to a first user; responsive to the first user approving the suggested activity type, initiate an activity session of the suggested activity type, and provide a recording of the activity session, the recording comprising information on at least one of the following: a route taken during the activity session, a metabolic rate or metabolic effect of the activity session, a quantity of energy consumed during the activity session, a sound recording obtained during the activity session and an elevation map along the route taken during the activity session. 25.
